Hello. I've used fly x/black glass. was smooth enough but I wasnt completely satisfied. I went to apex. That was a good rom no issues there but I started getting the "change the rom bug". It was smooth with good battery life. Went to rubix with numerous themes. Very smooth and fast, great battery life. Liberty came out and of course had to try that. It was both good and medium. I didn't get as good battery life and I got quite a few random reboots. However, theming was a breeze.(I never soft bricked my phone forgetting to mount and such) The toolbox is the absolute shizzle. Makes setting your phone up SO EASY. Rubix 1.97/Blue ginger is where I am now. (I just couldn't live with the Liberty reboot thing) I may go back to check the Liberty update out. Its a brand new rom after all and the devs there work their butts off. Whatever you choose, please donate to these folks. They certainly work hard, help with issues and make our phones soooooo much better. We have to support their various Red Bull, beer and food habits! I haven't tried dark slide or tranquility but they certainly seem to have fans as well. Hope this helps.
