lithium all the way, but bugless evodroid is awesome in its own right. tried simply stunning and it force closed all psx4droid roms. might give insanely clean a run, but i always keep a lithium mod nandroid backup along with bugless.
Chevy already put out an update that fixed psx4droid. Its a pretty sweet rom. It has built in update notification. All you do is check chevyno1 tools every few days and it tells you if there is an update. Plus it lets you mod the status bar like cyanogen but there is no reboot required.
