If you have 4G in your area or will have it soon, get it, otherwise you're paying more for no reason. All I know is that I hate typing on my Hero... SenseUI is amazing and all but its so annoying to text... The Moment really makes it so much easier to text, but it takes some time as the layout is really different than the TP2's.
So I guess it boils down to your needs;
Bigger screen
Faster Proc / More RAM
Better Camera
4G, when available
More internal storage
Or
Better looking screen
Cheaper
QWERTY Keyboard
Might also want to check out the Evo forums to see what people are talking about and if there are any big problems
