Hello guyz..what the best ROM that optimize the function of SG2 rather than make SG2 look nice with all the icon and graphics??

PM me ya..i'm flashing my SG2 since last monday..hik3..not using Batista v1.2..sadly when i open d channel list in radio..pop up said 'the application FM Radio has stopped unexpectedly. please try again later'.it kind of annoying..arrrggghhh...

and how i gonna roll back to original ROM..
