Diamond vs TP for daily use?

[Scrotum]

So I've come up on a free Diamond, cousin doesnt want the one Assurion is sending him so im giving away my old Vogue for it.

I am wondering how many have had both the Diamond and the TP and which one worked better for daily use? I use my phone mainly for email and tnd calender at work, along with about an hour of phone calls a day. Battery doesnt concern me as I have a charger in my office, car, and work car. Aside from the keyboard are there many differences between the two that may affect fuctionality?
