As stated... also this type of question is not allowed here. Answers can be subjective. It's up to you to read the threads and try roms out yourself... see which you like best.
**I will give a tip though... the best roms are usually all on the first page of the rom threads (as have the most users and support). So look there.
If you need help, check the FAQ first for whatever ROM you're on. Then ask questions.
