In my experience, the speed increase for non-game applications is far better and the lack of Microshaft overhead makes for a nicer experience. Until I get another Amiga, I'm making myself an AMD machine with Amithlon I can use for tinkering and boredom, and maybe development, if I can find some good tutorials for 68k assembly and C coding on the Amiga, then maybe I can try my hand at porting some applications for use on classic amiga, Amithlon and MorphOS as I alread have a MOS machine.
