custom firmware help

can anyone help me plz. fairly new to this but have sum knoleadge about this but need bit help, want to upgrade but overall which is the best cfw to upgrade to and why. i'm on 3.03 at the mo. hav upgraded one b4 to 3.03 cfw, but like i say what's the best one. thanx 4 the help.

the best cfw right now is 5.00 m33 that is if u would manually patch every new game.. and since ur on 3.03 im guessing u dont play new games so yeah 5.00 m33...

If u can resist NO ONLINE PLAY then I advice u to go to 5.50 Gen-D
