I tested the Darky's v5.2 ROM and now Doc's v3.0.1 ROM. Below is my opinion in points.
Sorry Darky but Doc's ROM seems to be a little faster..
Darky's ROM is very nice (Gingerbread theme) and animations are amazing. But Doc's ROM have Zeam which is much better than Launcher Pro etc.
Doc's v3.0.1 ROM - XEE
Darky's v5.2 ROM - KOR
I hope I helped you, Darky.. Good luck..
