What is the best smartphone for tmobile?

I have a $500 credit line upgrade available and was thinking of a smartphone. My sister and her husband have the myTouch and they really like it. If you have a smartphone, which one do you have and what do you like/not like about it? Thank you. (:What is the best smartphone for tmobile?

I am on Verizon, but they have similar phones. I am constantly torn between the Droid phones (like the myTouch) and the Blackberry phones. Let us know what you decide because I am always looking for opinions! :) But those are my top two choices.
