PS3 vs 360 emulation on (Linux) PC?

Been getting in the mood for an Armored Core 4 run and there is zero chance I ever dig my PS3 out of the closet ever again. Also more stable framerates would be nice.

So, these days, which emulated console (and emulator) is “best” for this generation? My assumption is 360 because of the CBE but the PS3 was a REAL sicko console and has relatively little backwards compatibility, so that might have been a bigger motivator for the development community.

Thanks
