Had the 64GB Verizon and just returned today for 64GB AT&T. Not in an LTE area for either in NJ but AT&T HSPA+ is SO much faster than Verizon 3G. It's 7 to 10 down where Verizon is 1.5 down at best on my speed tests. I know this because I put an AT&T card in the VZW iPad that I had. I just decided to swap it out because I didn't want to go back and forth switching sim cards and if I need hotspot feature I can always use my phone for that. Further, I'll have an upgrade on my phone in July. I'm guessing new iPhone will come sometime after that so I'll have Verizon 4G LTE on my phone too with an unlimited plan. Best of both worlds as some have said.
