I'm in the DC suburbs and am happy with T-Mobile. At my house Verizon has NO signal at all. So clearly it's a location-dependent issue. Carrier diversity does have its advantages in other ways. I was in NYC during the earthquake and had no problems with text or data immediately afterwards, even took an incoming voice call. Everyone around me with iPhones on AT&T or Verizon couldn't do a thing.
