We have seen comparisons between newer versions of these OSes on NG Amigas. How about some benchmarks between MorphOS 1.4.5 and AOS 4.0 on a classic Amiga setup? Who's up to the task? 
I can tell you one thing for sure (depsite what Karlos may say...

) OS4.0 on a classic Amiga without an RTG board is slower than a dead tortoise thats been nailed to a lump of wood...
