Cable broadband may have more subscribers, but fiber customers remain more content with their connectivity, per the latest survey from the American Customer Satisfaction Index (ACSI).As in last year's ACSI survey, fiber broadband's fast speeds—not just downloads but also uploads—place it far ahead of cable. AT&T Fiber ranked highest, with a score of 78 out of 100, followed by Google Fiber (GFiber) and Verizon Fios at 76 each. Third place goes to an unlikely company: Comcast, whose small Xfinity Fiber network earns a score of 75.Comcast's mainstream Xfinity cable service, meanwhile, comes away with a mediocre score of 69. That lands the Philadelphia firm in the middle of a group of cable operators in the non-fiber category of ACSI's report: Cable One's Sparklight and Charter's Spectrum, tied at 71, and Cox, 68. (On Friday, Charter announced plans to buy Cox, a deal that would make the combined firm the biggest cable broadband service.)The top two non-fiber services, however, are both fixed-wireless 5G: T-Mobile's leads the category at 78, with Verizon right behind at 77. AT&T, which sells a hybrid-fiber service it confusingly brands as just "AT&T Internet" as well as "AT&T Internet Air" fixed-wireless 5G, has a less impressive 70. Fiber providers did well in PCMag's Readers' Choice awards for 2024, with GFiber winning best overall and best fiber ISP, followed by Verizon as best major ISP. Our Best ISPs of 2024 survey had similar results, with GFiber winning Best Major ISP and T-Mobile taking Best All-Around ISP. ACSI's survey results line up even closer with our readers' picks in wireless carriers and wireless resellers, also known as MVNOs, short for "mobile virtual network operators." Once again, the ACSI finds people like wireless service better when they pay a different company for it: The highest-ranked service, the AT&T reseller (and regular occupant of a top spot in our Readers' Choice lists) Consumer Cellular, earns an 82, while AT&T itself gets a 74. Recommended by Our EditorsAT&T-owned Cricket also does better than its parent firm with a score of 76.T-Mobile does best among the big three with a 76, but its Mint Mobile brand does three points better. And while Verizon comes just behind T-Mobile at 75, Spectrum Mobile, based on resold Verizon capacity, also comes in three points above. Two prepaid services owned by Verizon—Straight Talk, 78, and Tracfone, 77—also do better than their corporate parent.ACSI chalks up slight declines across the wireless industry to "call quality and network capability issues" that hurt both the wireless carriers and the services reselling their networks. This latest ACSI survey also assessed customer happiness with smartphones and smartwatches. In the former category, Apple and Google tie with scores of 81, followed by Google and Motorola tied at 75. In what should surprise nobody who has ever picked up a phone, respondents are least satisfied with battery life, although that 77 rating still beats the wireless industry's sector-wide score of 75.We can endorse this comment in the ACSI report: "Customers have largely shrugged off AI-driven enhancements to date and continue to value the practical basics of calling ease, texting ease, and phone design while craving better battery life."The latter category, a new addition to ACSI surveys, has Samsung wearables leading Apple, 83 to 80. Google's Fitbit comes in third at 72; the survey did not cover Google's Pixel Watch series.ACSI, based in Ann Arbor, Mich., collected 27,494 surveys from its pool of respondents, picked at random and quizzed via email from April 2024 to March 2025.
