I like sense more then blur but I have VZW so I have the DX. But if I were to go to Sprint, I would choose Evo. I like the bigger screen, typing is much easier in portrait for me.
But I would not use the front facing camera, no one I know has it. I don't even use the webcam on my laptop ever except to test out certain program. Think the webcam on my laptop has around 20 minutes of use in the past year.
