Can't speak for Morphos but it will run on AmigaOS4, **but** oddly enough the AmigaOS4 version will run much better, not just faster because it's native but also it makes better usage of the more modern API functions and can promote screens to 24bit allowing smoother integration (no monitor resync it screen switching) and true colour previews in the Story Board.
The 68k version will attempt to run in low memory mode on AmigaOS 4 because it can't find any chip mem the PPC build knows about this and doesn't panic :-) The PPC version will never accidentally run the angus based blit library, so avoiding a crash the 68k can have when running on an OS4 machine.
If you buy both you get a discount...
I can donate my Efika (PSU, Radeon and HD included) if you want to check it out. It has no key but 30 minutes is enough to check if it runs or not.
