Compare CenturyLink and Optimum head to head

We think CenturyLink is the way to go if you had to choose between these two providers.

The provider has excellent fiber options, including a bargain-friendly 500Mbps plan and a gigabit plan that gives you fantastic symmetrical speeds. You also don’t have to worry about data caps or annual contracts. We’re not so keen on CenturyLink’s DSL plan, though, which is much slower and yet costs the same as the 500Mbps plan.

Optimum has extremely fast plans, including multiple multi-gigabit options. It also has a two-year price lock on its plans, which is a big plus considering how many providers like to regularly raise their prices. But Optimum gets much lower customer satisfaction scores in critical categories like price and overall satisfaction, suggesting that customers aren’t the provider’s biggest fans.

Pros and cons: CenturyLink vs. Optimum


  • No data caps on any plan
  • No cost on installation and equipment for fiber gigabit
  • Super low price for 200Mbps fiber plan


  • Slow DSL speeds
  • Limited fiber availability


  • Two-year price lock
  • Gigabit and multi-gig plan options
  • No data caps or contracts


  • Low customer satisfaction ratings
  • Lack of clarity about whether customers have fiber or cable

Plans and pricing: CenturyLink vs. Optimum

CenturyLink has been expanding its fiber offerings lately, giving you more variety and lower prices (at least in some markets). It also has a middling DSL plan but we only recommend it if your options are limited. Optimum offers both fiber and cable internet, with excellent introductory prices and multi-gigabit speeds in some areas.

CenturyLink FiberGigabit Internet$75.00/mo.§Up to 940Mbps

CenturyLink’s fiber plan gives you lots of speed at a fair price. The gigabit plan is its most popular and well-known offering; you can do pretty much anything with 940 Mbps speeds. And the monthly price is hard to beat.

Even better, though, is the 500Mbps plan. It costs just $50 a month, making it one of the best-priced fiber plan you can find anywhere. And 500Mbps is more than plenty for most people, giving you ample bandwidth for streaming, gaming, and more.

If you can’t get CenturyLink fiber in your area, you have to settle for the provider’s DSL service, which is only worth getting if you have few other options. DSL is a fusty old connection type built on landline phone infrastructure, and its speeds just don’t cut the mustard for a lot of netizens. Avoid it if you have a large household or need a reliable connection for streaming and Zooming.

Pro tip:

CenturyLink’s gigabit plan is probably its best plan, but you may be better off getting a slower fiber plan if it’s available so you can save money. Use our “How Much Internet Speed Do I Need?” tool to decide what’s best for you.

Optimum beats out CenturyLink on introductory prices and speed options. You get a lot more to choose from on an Optimum plan, and you get more promos and deals too. And while Optimum used to hit customers with steep price hikes after 12 months, it recently introduced a two-year price lock for new customers, making its plans much more affordable and reducing headaches over inflated prices.

If you need speed, Optimum really is the way to go rather than CenturyLink. In addition to the usual 940Mbps gigabit plan (a standard offering for most fiber and cable providers at this point), Optimum has also joined the ranks of providers like AT&T by offering up 2,000 Mbps and 5,000 Mbps plans. Do you need internet that fast? Not really. Can you find those speeds in all of Optimum’s service areas? It doesn’t look like it. But it’s still kind of impressive that Optimum has rolled out these capabilities for some customers.

CenturyLink and Optimum both have fees for installation and equipment—although Optimum definitely goes lighter on the equipment fees. Renting a modem is $5 cheaper per month and you don’t have to pay for a self-install kit like you do with CenturyLink. (However, CenturyLink does waive the cost for modem and installation with the fiber gigabit plan.)

Buy your modem and router to save on extra fees

While you can rent a modem and router from your internet provider, consider buying your equipment instead. You don’t pay rental fees every month, plus you have more flexibility and options when it comes to picking a router that meets your specific internet needs.

The best standalone router you can get is the ASUS ROG Rapture GT-AX11000, based on our tests. It checks all the right boxes in terms of speed and features—it even supports mesh networking. If you’d rather have a mesh system, the TP-Link Deco XE75 Pro has our highest score out of all the mesh systems we’ve tested. Want a router designed specifically for gaming? The MSI RadiX GRAXE66 is an awesome pick.

Customer ratings: CenturyLink vs. Optimum

Overall RatingSpeed RatingPriceReliability RatingCustomer service Rating

Both of these internet providers end up at the bottom of the pile in our annual customer satisfaction survey—neither perform as well as AT&T, Verizon, or T-Mobile.

However, when faced against each other, CenturyLink edges into the lead in most categories. It beats out Optimum for reliability, customer service, and overall customer satisfaction. CenturyLink comes in well ahead of Optimum on price, actually making the top five in that category. We suspect that CenturyLink’s satisfaction ratings go down because a lot of its customers have middling DSL service, but CenturyLink also has a much faster and more reliable fiber service that customers have given high marks in the past.

Optimum has some well-priced bundle options if you want to pair your internet with a streaming or cable TV plan. You can also sign up for a mobile phone plan through Optimum, letting you get a cell phone plan for just $45 a month (or even less if you add more lines).

CenturyLink doesn’t really offer TV and internet bundles—you technically can pair your internet service with DIRECTV, but you order them à la carte like any other service and you have to pay full price for both.

Internet types: CenturyLink vs. Optimum

Internet typeOrder online
CenturyLinkFiber, DSL
OptimumFiber, cableView Plans

CenturyLink offers fiber and DSL internet, while Optimum has fiber and cable internet. Fiber is the fastest type of internet you can get, with speeds going up to 5,000 Mbps and symmetrical upload speeds that are excellent for Zooming, social media, and livestreams.

Cable is the second best connection type. It’s still fast and reliable, just not as fast as fiber, topping out at 1,000 Mbps download speeds and usually 50 Mbps uploads. DSL is the slowest option of the bunch, delivering max 100 Mbps speeds over aging phone infrastructure. Get DSL if you have few other options or live in a rural area.

Data caps: CenturyLink vs. Optimum

Neither CenturyLink nor Optimum have data caps on their internet plans. That means you can use the internet as much as you want throughout the month without worrying about overage fees or throttled speeds.

Here’s some more great news about these providers—neither one requires you to sign up for an annual contract. You can cancel your service any time without having to pay early termination fees. That gives you more flexibility to sign up for a plan for just a few months or to switch providers if your service isn’t working as well as you’d like.

    CenturyLink and Optimum both offer similar options for installation. The best way to go is to opt for a self-install kit that lets you plug in the modem/router and set up the wiring yourself. It takes less than an hour and you can set it all up with the help of an app on your phone.

    Sometimes technical stuff can be too complicated or frustrating to deal with, and if that’s your situation, then you can pay a $99 fee with CenturyLink or have the fee waived when you order online from Optimum to have a technician come over and set everything up for you.

    In some cases, you may need to pay a higher installation fee to cover the cost of installing more complex things like an optical network terminal or wiring that leads out to a node outside your house. This is most likely to come up if you live in an older home or apartment that isn’t already set up for fiber internet.

    Availability: CenturyLink vs. Optimum

    CenturyLink has a fairly large nationwide network, covering parts of the East Coast, South, Midwest, and West. Optimum is available in 25 states, including large parts of the South, West, and East Coast. Use our zip check tool to see what you can get from either of these providers where you live.

    Final call: CenturyLink vs. Optimum

    Optimum has some great offerings when it comes to speed and prices, but the low customer satisfaction ratings make Optimum’s deals less desirable in the long run. CenturyLink is really the winner here—specifically its fiber offerings, which get you primo service with fast speeds and reliable pricing. If you had to pick between Optimum and CenturyLink’s sluggish DSL, though, we’d go with Optimum.
