Should i dump Verizon and come to Sprint for HTC Touch Pro?

[MaybePurple]

Sorry for asking a newbish question, but i am in market for a new phone.
HTC Touch Pro looks like a great phone, but Verizon has severly crippled it. The only reason i am with Verzion is because of their coverage, but isn't Sprint just as good? Or am i wrong.

I would like to use the phone for being able to surf the web on the go, but also i'd like to tether it to my laptop for internet access.
Another thing, and i don't know if it's possible, i'd like to use it as a GPS reciever connected to my car computer with bluetooth. Is that even possible?

Thanks in advance!
