Still, the differences are in the core mechanics which make them very different games. I would be surprised if there's much overlap between the player bases at all, so I still see no point in saying that Nethack is a better game since it appeals to totally different players.

I would be pretty surprised if, of those who played Nethack around the release of Diablo who also made a habit of purchasing Windows games, there wasn't a majority that also played Diablo.

I agree that the two are sufficiently different, and sufficiently well executed examples of their species, that personal preference between the two is likely to be dominated by the differences that cannot be reasonably labeled "quality".
