I have a Touch Pro, a Treo Pro and a Pre. If you're browsing alot the touch pro has by far the best screen. Also it's much easier to me to text, etc. on the touch pro. Having said all that Sprint replaced the first two I had due to the keyboard failing.
As for the Treo Pro, I find it to be a much better all round device. I prefer it to my Pre actually. With the availability of custom roms for the Treo Pro and the hacks and fixxes I wouldn't consider going back to the Touch Pro. Last and perhaps most importantly the battery life of the Treo Pro is exceptional. Without a custom rom the Touch Pro didn't make it 6 hours without having to charge.
