Agreed. I wish someone would do a map that would compare the locations where you're likely to get 5mbps. At the moment, AT&T really wins there.
I also don't know if folks really understand that in the areas Verizon doesn't have LTE, their 3G speeds are insanely slow (compared to AT&T). Having switched both my iPhone and iPad to Verizon last year (after five years on AT&T), it was a real eye-opener for me.
I live in a location where Verizon has had an LTE "dot" for about a year now. The quality of their LTE network here is *nowhere* near the quality of their voice/3G networks here. That's just the nature of the beast, when it comes to rolling out new technology. Ultimately, that means there are times where my Verizon LTE iPad falls over to the Verizon 3G network. That is a >>>horrible<<< experience. Rarely breaks 512mbps around here.
512mbps?? good god. ive never seen that on any cable internet around here, much less a phone.
