Both ATT and VZW use 700mhz for LTEYou guy's do know that ATT also has LTE, and that it is faster than Verizons?
Switching from ATT to Verizon is good if you get better coverage where you live. But switching for the sake of switching is not a good idea. Verizon throttles too. Same as ATT.
ATT LTE to 3G HSPA+ speeds is not a big drop off in data rates compared to Verizon. On verizon you can go from 20Mps down to 2Mps down. And until Verizon has nation wide and complete 100 percent LTE coverage your performance will suffer compared to ATT.
Heck, ATT HSPA+ is almost as fast as Verizons LTE.
LTE speed for VZW and ATT depend to avail 700mhz spectrum depth in each market/city. Also keep in mind that att's LTE is pretty empty now.
Overall VZW will have better coverage and spectrum depth and speed.


Since you think att is faster, i will leave this here for u LOL
