Best rom with sense for my TP

[failurbydesign]

Just picked me up a TP on eBay (ditched the q9m for the omnia, ditched the omnia for the TP), anyways there are some really cool roms, but i wondering what the general like is for a rom with sense? I don't know the differences between sense 2.1 and 2.5 and if* it could slow the phone down, but im willing to try a few roms if that's what it takes!
