Yep, Atari Falcon had the best graphics by far, as well as a built in DSP chip. Had it ran Amiga OS at the time, it would have been the best option all around me thinks.
Don't forget the Atari Falcon was limited by a 16bit bus...
I have never seen an Acorn. I will try RiscOS when I get my RPI, and I suppose I can compare it to AmigaOS.
