Most Up-to-date/Stable Emulator for SNES and Genesis?

I know I asked a similiar question for something else before, but I can't help but ask again, since I'm just about to come. Into the Genesis scene, and I want the most stable Genesis emulator.Also, It would help if you posted links to websites where i can find these. Google doesn't help me get up-to-date stuff and that one emulator website doesn't do jack.

Fusion is best for genesis I think, its what I use anyway.
I prefer zsnes for snes but ive been told bsnes is the best, ive never had any problems with zsnes though.

Thanks.
