I don't think that you're fair to hyperion, eyetech etc... AROS is... well nice... but AOS 4 feals like years ahead of it. It's really very, very nice. I simply love it. Yes I've been using WinUAE on a modern PC and it's like a mix between my a4k with a Voodoo 4, SB 128, networkcard CSPPC with a 060 and a 233MHz PPC and my A1... It's slower than my A1 but faster than my a4k... and it isn't even close to the fun that I got with my A1.
AOS 4 is AOS only so much better than 3.9. I can't believe that any solution can bring back the amiga feeling in a way that AOS 4 can.
IMHO offcourse
