I use Amiga emulation for playing games, period. I don't give a hoot about the apps, I have plenty of superb ones for the Mac and PC. So WinUAE is better, mostly because of the new save state! I can stop playing Turrican or Fire and BRimstone in the middle of a volley or slash, and return later
I must say, I enjoy Amiga games immensely more than I do modern (or old) PC gmaes!
