Verizon vs. AT&T vs. Sprint vs. T-Mobile: Who's best in your city?

It's a clash of the carriers! Gearheads love to compare the nitty gritty of different smart phones. But what about the networks? Without a strong carrier presence in your city, many of those smart phone features go to waste. So, if you're unhappy with your current network, moving to a new state, or drooling over a phone on a different network, here's a quick carrier cheat sheet.

Consumer Reports' Winter 2010 reader survey tracked carrier quality in 26 metro areas. Here's its city-by-city breakdown. Note: This report shouldn't make or break your buying decisions. (Here in Boston, plenty of Monitor editors are happy with last-place AT&T.) But the list might help focus your search for the phone that best fits your life.

Atlanta: Verizon is the only carrier with any positive ratings. T-Mobile came in second, followed by Sprint, then AT&T.

Boston: Beantown is definitely not "the Hub" of cellular networks. No carrier got a positive rating. Verizon, T-Mobile, AT&T, then Sprint.

Charlotte, N.C.: AT&T and Sprint both got below satisfactory "dropped calls" rating. Verizon, Sprint, then AT&T.

Chicago: Verizon again leads the pack. T-Mobile, Sprint, and AT&T follow.

Cleveland: Verizon, Sprint, then AT&T.

Columbus, Ohio: No carrier got a negative mark, but only Verizon did well. Verizon, Sprint, then AT&T.

Dallas-Fort Worth: Verizon gets the best possible grade for "dropped calls." Verizon, AT&T, T-Mobile, then Sprint.

Denver: AT&T gets its worst rating in the nation, with black marks in "no service," "dropped calls," and "static." Verizon, T-Mobile, then AT&T.
