I'm using MorphOS2 on Peg1, it works fine and I'd even say that it's the most comprehensive OS release on Amiga front ever! I'm not sure if you can get most of it with Efika though. As it's bit limited in some ways and there seems to be some small issues on some users too. But might be cheap way to get into OS etc. But I haven't seen Efika ever, so listen other comments on that
