You might want to check with current T-mob owners in your area.
Sometimes T-mob is better than AT&T. A tower here or there makes a big
difference.
UMTS doesn't have a hard distance limit like GSM. With GSM, regardless
of signal strength, you need to be within 35km. That is the theoretical
limit based on timing, and you get very close to that in real life. But
UMTS is similar to CDMA. Its limit is based on SNR, though in urban
areas probably capacity is a bigger deal. I don't know if it throttles
you down with SNR. The only phones I've owned drop you down to 2G if the
3G is too weak.
There are a few crowd sourced apps for sharing cell phone reception
quality, but there just aren't enough geeks using them to make them useful.
www.cellumap.com
comes to mind, but there are others.
If your goal is to use once device for home and mobile, i.e. skip out on
DSL or cable at the house, forget it. A bandwidth hog on wire is
tolerable, but I doubt any wireless company will tolerate such users.
Like I said, even T-mobs unlimited plan is throttled.
I'm grandfathered in at $25 for unlimited data, but I don't abuse it.
