I have been on Cognition for a little while and it was very good. Smooth and fast. I wanted to shake things up a bit so I tried Paragon RC4, holy crap. It was awful, the notification bar was so laggy when you drag it down and the theme and look of it wasn't very nice IMO. I couldn't get my phone to go into download mode either while trying to flash a diffrent ROM the right way. I decided to skip some steps and re-install Cog. It worked luckily and I was able to get to download mode to install a ROM the right way. I decided to give Serendipity a try since reinbeau keeps on stating that it is so good, so I gave it a shot. I love it. It is so smooth and I love how it has a sort of gingerbread theme to it. Everything is smooth and fast and I love it. If you are wondering what ROM to try next and you haven't tried Serendipity. GO FOR IT! You won't regret it. Thanks to reinbeau again!
