I've had a diamond for a while and I've used a touch pro. IMO the Diamond is preferable because its smaller, easier to carry around, easier to text (with one hand), easier not to drop, easier to pull out of my pocket.

TP has the hard qwerty keyboard and a bigger screen, so it depends what you want in a phone. Personally I prefer a soft keyboard (especially ezinput 2.1). Out of all the phones out there (including the pre and hero) id rather have a diamond, and much rather have a diamond2 over a pro2.

edit: although I hear good things about the pre, its faster, smoother etc... I prefer all the WM mods and roms and options. The Hero has a very weak resolution and some videos show it to be sluggish at times, not to mention that stupid chin
