Best Android on T-Mobile?

[Captain Marvelous]

Hello my contract is up for T-Mobile so it's time for a new phone. I'm upgrading from a sidekick 08, si bet any phone is better than that! I've been wanting the Blackberry 9780 but after reading posts in this forum about Androids, I've been changing my mind. So far the only phones that interest me are Nexus S, Mytouch 4G, Samsung Galaxy S, and G2 (not liking the design though).
I want to make a good decision, so are their any T-mobile users here who absolutely love their android phone that they can recommend to me? I have yet to play with these phones, but I know I want one. I don't mind if it has a keyboard, I just want a phone that I will love for the next 2 years. Haha
Thanks in advance!

i love my vibrant. had it for almost a year now. its a bit laggy once in a while, but thats cuz of all the random apps i forget to close or have running in the background.

the screen and the weight of the phone are kickers for me. the phone is deceivingly light for its size.

The G2X is a great vanilla dual-core beast if you're in to those things.
