There are 2 that I switch back & forth with: BlackBean6 & Metropolis. Now, on BB6 I do OC, but I don't have to. Both ROMs run my games real fast & smooth. Metropolis actually runs them a lil better.
That's mine. You have to try out what is best for you. Try them all out & make a backup. Then go back to what works best for you, & delete the others.
BTW, welcome to the forum, with the best phone & support group.
