First of all I do not really worry alot about batt. I look more for speed, performance and stability for my device as i got charger everywhere.

Anyway here is another evaluation base on internet usage.
1) Unplug from charger at 98% batt went to sleep
2) Wakeup 92% batt.  For me this is not normal usually its just 3% drop. Main suspect dual core script have been removed. Have added it back in to observe if any diff
3) Screen on time about 52 mins
4) Internet surfing (dolphin, xda app, facebook, market, samsung app) about 50 mins including download of about 20mb
5) Flash one kernel and reboot (big drop in batt graph)
6) Reboot another time to activate dual core script (small drop in batt graph)
7) End up 70% batt

Again dunno if it means anything to you.

[attachmentid=2451022] [attachmentid=2451023]

Dual core script to totally shut down second core in sleep. Dunno how to compare to stock cos only use for 1-2 days quite some time ago. You will have to try for your own.

Actually hor, i think all cooked rom about the same. Go with those that have least bug. Or if you like theme those thats got lots of theme. Its your choice.

I pick touch-x cos i never got issue with it. Plus i like siyah kernel (which is mainly developed base on touch-x roms) cos it got lots of feature and the only one that did not cause my device to freeze.
