Big difference because they're still national plans.
Verizon FiOS is not a national or even Verizon wide plan. AT&T U-Verse is not a national or even an AT&T wide plan. Don't even think about cable companies having the same speeds and prices everywhere. Lack of effective competition is the reason why U. S. broadband isn't better.
Of course it is. FiOS plans are nearly standard in every FiOS market and the same with U-Verse.
False on its face. FiOS plans follow a close pattern to competition. There's about two to three templates Verizon follows, but which template they choose from for each area has a lot to do with competition, and the templates are far different from each other.
Who cares what AT&T does with U-Verse -- that whole product line is a low class tier anyway. It doesn't really count. It's slower than anything else.
False on it's face. FiOS tiers are nearly universal across all FiOS markets. They are 15-25-35-50 just about everywhere if not everywhere FiOS is available.
And 18-24Mb U-Verse is slow compared to what exactly? They are also getting ready to deploy bonded service.
