Can anyone advise on Sprint vs. T-Mobile in terms of reception quality in this area? I'm less interested in your experiences with their customer service and such, but of course, I can't stop you from posting that stuff anyway ;) so have at it.

I have T-Mobile at present and received a pretty tempting promotional offer to switch to Sprint, but I'm leery on the "if it ain't broke don't fix it" principle. I've never had much trouble with T-Mobile reception (or customer service). Am I going to have reception issues with Sprint?
