In need of some opinions for a sprint smartphone

[unkledude]

I'm looking to upgrade my HTC hero to another smartphone from Sprint. I've basically narrowed it down to 4 phones. I use my phone for e-mail, text , gps , calling , surfing and some minor picture taking. What can y'all tell me in +'s and -'s of each.


1) evo 4g
2) evo 3 d
3) Motorola photon
4) Samsung gs2
I don't know how to root , and I don't know enough to say that this screen is better than another.

Thanks to all who reply on advance
