1- Miui was the coolest one, Still got problem with how iOS-y it is but it had a very interesting UI and almost with no problem ( it was a little slow compare to other roms and somtimes become blank for a moment), overall it was very tempting. I might try that 1 week trial to see how it goes.
2- LeeDroid was the same old htc sense, though it was great and fast but after what I saw in Miui it just looked so lame to me

I think I need something new and different.
3- Oxygen functionally was the best. it was fast, smooth, bug free and everything was working properly. no problem with market, bluetooth or the browser and it didn't even looked much different from CM7. it was exactly what i was looking for but... not as cool as MIUI
Now I have to decide between Oxygen and Miui.
