What is the greatest cell phone provider in U.S.?

I know it's a general question but I was wondering what company offers the following:
1) Best voice technology
2) Great coverage
3) Great Technology (great phones).

What's better GSM, TDMA or CDMA? I live in NE so it's kind of hilly, thus I want a frequency that operates nicely in a hilly/Mountaineous terrain.
Is GSM better than CDMA?

Will GSM coverage of AT&T every expand? Does it work well in NH?

Thanks

I use US Cellular and have been all over the country with it and it works very well. It uses the new tower triangulation technology and I just don't loose signal anywhere anymore.I have used it from oregon to california over to florida with no problems. I live in oklahoma now and it works perfect here to. and they use seven or eight different phones, just whatever your preference is.

I would never trust AT&T! They have screwed me many times over. Others I know have had same problems with them. So my advice hang-up on AT&T.
