As many have said, it is not emulation. It is re-creation. Like all re-creations how accurate it is depends in the information you have on the original.
AGA was also a re-created Amiga chipset but the engineers had the original design chip schematics, something the developers today do not have.
I'd be surprised if anyone would disagree that it will be hell of a lot closer to the original hardware that we love than WinUAE
I disagree. :-P
Why doesn't WinUAE 'feel' like your original Amiga? I ran WinUAE on my Iiama Vision Master 450 Pro at 50Hz with VSYNC for many years and it felt very close. Could it be your setup? I used a monitor capable of an exact multiple of the Amiga framerate (50Hz, 60Hz, 100Hz) forced this using powerstrip and enabled VSYNC. This makes all the difference to me.
