I personally like theKompany\'s rom best right now... it\'s fast, stable, haven\'t had a single hardware compatibility issue, and it\'s beautiful.
Though I can\'t say that I\'ve given OZ a fair shake yet... my biggest grip is how it handles wifi connections... since I connect to 4 different wifi APs (2 different home connections, starbucks, work), and the best ROM in my opinion for quickly switching between wifi connections is a 3.10 ROM (sharp, cacko, theKompany, etc.). Though now that I have my 760, I just use that to connect to all my different APs, and can finally try out OZ on my 5500!
Why don\'t you try a few out, and see how you like them... it\'s best to experience the differences so you can make your own judgement.
best of luck!
