It is a pretty good phone from the reviews I have read. The only draw back is that you can't buy or test it in T-mobile stores. But I saw that the HTC Droid Incredible is similar, just made for Verizon. So you could test that phone out and see if you like the Droid Incredible. Since the features are similar I wouldn't an issue in testing it that way.
I would say to avoid the Motorola Cliq because I have read that the motoblur feature drains the battery, where as HTC (makers of mytouch) focus on batter life. So Snapdragon (found on the Nexus One) was created with the intention of longer battery life.
I probably didnt answer your question completely but hope it helps!
