Seeking Cellular Service Recommendations for Fairfield County

I plan to take advantage of the impending number portability hoopla to change my cell phone service. I’m currently with Sprint – my problem is that the coverage around home is spotty and it recently seems to have gotten worse. The leading contenders are Verizon and AT&T. Consumer Reports seems to like Verizon, but AT&T has more aggresive pricing on phones. Feel free to comment if you have experience with either service in Fairfield County, CT or New York City.
