If you are close to a major city, your coverage should be excellent. Here's what I've experienced:
Good:
San Fran (BUT the hills create deadspots,experienced the same dead spots on a borrowed sprint phone, same with AT&T)
Excellent:
Atlanta, Denver, Washington D.C. (HSPA+ cities)
Great:
Omaha, Co Springs, Albuquerque, Sante Fe (Mostly 3G, sometimes back to EDGE)
Bad:
On the highways between major cities, most of the time roamed on EDGE, and sometimes lost all signal, but i don't care, i don't take many roadtrips
