I live in NYC, I know with voice, the ATT service I have for my iPhone sucks when I am in buildings and Verizon seems to get better Voice reception. Anybody from around the NYC area pick ATT over Verizon besides being grandfathered into the unlimited plan?
I am in NYC and have an AT&T iPhone (which is 3G obviously, not LTE), and a Verizon Mobile Broadband modem which is LTE/3G.
For a very long time this was a no-brainier: AT&T was very, very bad. It has improved a lot recently. I no longer find myself in spots where my phone gets almost no bars anymore. Still, I think Verizon is better. LTE is almost everywhere, and 3G absolutely everywhere.
If we keep in mind that iPhone is very popular in NYC (probably more than anywhere else in US), combined with the fact that people spend more time being out and about and using 3G rather than sitting home and using WiFi, and with the fact that NYC is the most densely populated area in the country, Verizon getting the iPhone went quite a way in equalizing the network loads which were previously weighing quite heavily on AT&T.
Further, people say that AT&T LTE is faster, and my impression is that eventually, it's coverage will be as good as Verzion's (but they are not there yet).
Still, I ordered a Verizon LTE iPad, but here is what played a major role in my decision: I will be getting a new AT&T iPhone when it comes out later this year and it will quite probably have the LTE. So, I wanted to end up with one of each. Also, unlike AT&T, Verizon offers a 10G plan (for $80/month). I know it's not for everyone, but I do use a lot of data, and extra 5G for $30 is a better deal than paying $10 per 1G in overage fees.
