well, i am all about performance...and looks too. i am running 6.5 that i cooked from ssk 3.1. i removed the htc phone canvas and ran the no push internet and resource proxy cabs. i also ditched manila once i found an app on winmo marketplace call "home screen customizer" or something like that. it allows you to run titanium and move panels around, delete them and add new ones such as an apps panel and weather panel. after doin all that my tp2 is very snappy, boots at 120mb and rarely drops below 100mb after a weeks use (however i am a lite user, mainly games and some news/streaming apps).
i created a nice looking windows dialer skin, and found a nice taskbar here at ppcgeeks. after doing all this i am very happy with my tp2 now. it looks great and performs great, and once i cook with the ssk 3.3 when its out i am sure it will be even faster
here's some screens:
