I ran Darkslide GB for a few weeks.
I loved how fast and smoothe it was, battery life was great. The problem is with the slide-down menu, you can barely read anything on it.
The other problem I developed after a while was my sd couldn't be read very much. At first I dismissed it as Flikie wallpapers causing my gallery to me sluggish, then it being a class 2 card. But after enough of everything, I sbf'd back and am currently stock without any problems.
The sd card issue really began to get old, every few hours I had to reboot the phone to get the sd card to read correctly. Stock doesn't give me any grief, so I'll deal with it until the next OTA update and see if anything improves.
