TweetI have AT&T (formerly Cingular) - they seem to do pretty well, they've hardly ever dropped a call on me. With them, I have nowhere near as many dead spots/zones as I did with Sprint a few years back - they were dropping calls all over the place. Not to mention, they're the ONLY carrier that does the Rollover thing where you can carry unused anytime minutes over from month to month - for up to a year from the month when you earn them. But now they're pushing their unlimited plan, which would make Rollover minutes irrelevant.
