I see people asking this a lot, so I thought I'd post the results of this Consumer Reports survey about cell phone service-- specifically the actaul service of the phone, so circuits full, dropped calls, static, and no-service areas are the criteria. This is according to a Consumer Reports SURVEY, so read into it what you will.
They sorted it by metropolitan areas; Portland wasn't one of them, but in Seattle Verizon and T-Mobile tie for first, and in San Francisco Verizon wins by a bit.
Just for the record, Verizon tops the list in every metropolitan area except Chicago, where it's behind U.S. Cellular. T-mobile is usually behind Verizon by a varyingly medium to small margin (Sprint took second in Detroit though, and in New York T-mobile actually took last). Cingular, Sprint, and Nextel's places all vary otherwise, but it looks like Sprint *tends* to beat Cingular and Nextel.
Also, just a reminder: MEETUP TUESDAY!
