Can someone give me a thumbnail on how to compare Cingular to Sprint? I have had Sprint for seven years or so but I am sick of

a) terrible (and I mean terrible) customer service
b) poor cellular service in unpredictable places
c) phones lag the rest of the industry in feature and design

I travel nationwide so coverage is important. Price is not that big a deal if I can keep a two line plan for less than $100 inclusive of tax, which is the company limit for reimbursement. I currently have 2000 (shared) anytime mins plus unlimited nights and weekends for $85, including a company discount. Pretty good deal but I think I can do nearly as well, as my company has a discount with Cingular as well.

Any suggestions on how to make the decision? I really dig the RAZR phone.
