I have FIOS gigabit and just got: 759 down / 914 up.

That's with active network activity, so that's not a "pure" speed test. But I've been extremely happy with Fios. In 5 years I haven't had a single problem. I haven't needed a technician to come out. I haven't had to call them and threaten to cancel my service so they don't raise my bill to some ridiculous amount. They haven't even changed my rate in 5 years! Switching from Comcast was one of the best things I've ever done. It's night-and-day. Even if your speeds stayed exactly the same you should switch just to not have to deal with all the other bullshit.
