Decided I want to update my psp, im currently on 6.20TN with psp 3000, so I wanna know which CFW is the best to use currently, which one is good and can use cheats, and can do ps1 popsloader , and can can fully use the CXMB, and has the permanent patch on the 6.60FW? I've checked out PRO but I just wanna be safe and make sure I pick the right one for myself.

btw, im on 6.20TN with the permanent patch installed, do i need to remove those two FIRST? or i can just go ahead and update to 6.60 and installed the best CFW?
