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..

GRAPHICS (animations)
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..
