i have a nextel and a sprint. i say if a bunch of your friends/co-workers have nextel then go with nextel. Walkie feature is awesome since you dont have to call someone, all you do is connect say what you have to say and thats it. If all your people have nextel then get the lowest priced plan that includeds unlimited walkie. That way you dont pay alot, and most of your comunications are going to be done over the walkie not the cell.As for coverage, just look at the coverage maps in your area and decide whats going to work best for you.
