Well... Let me ask one question... What answers did you expect
A list of 84 ROMs you could possibly flash onto your SGS2?
You ask 30 different people the question which ROM they like best, you get at least 20 different answers.
So, just read through all the [ROM] posts in this forum and find the one that is best for you. Everybody likes different aspects of a ROM.
If you have a question to a specific one, well... It's the same thing again. Search the respective thread and if you don't find anything useful, post it (But NOT as a whole new thread, please...)
