Well, I think I prefer the slightly less...uncanny character portraits in the EGA version. The rest of the game seems a bit of a wash; some of the backgrounds are a little more striking in EGA, some look much more refined in VGA. And the sprites look much better and more colourful in VGA. I don't think it suffered as much moving to 256 colours as Loom did (what that original thread was about).

And we should also remember that looking at it unfiltered on a modern display isn't really giving a great sense of the warm glow either version would've had on a CRT; neither of them really looked the way that video suggests, so it might be a bit misleading.
