I use 3.10 OE-A' because it has the 3.10 pops built in. I can play ALL the PSX games I like without having to mess with pops loader. I also don't customize the XMB, so it makes no difference to me that you can't change the top menu icons in 3.10. Then add the fact that 3.10 OE has the latest patches to video playback and fixes to ISO playing and you see that 3.10 OE is the way to go unless you NEED to customize the XMB for some reason.
