This is an excellent list.  I think only a minority of these qualities could be scored precisely, but I think all of them could be scored on some awful-to-excellent scale, so that while they may not be quite objective metrics, they're at least clearly debatable.

Complete objectivity is probably impossible here -- inevitable in a world where the concept of 'Rome' means significantly different things to the local authority, the ancient historian, and the tourist board.  But 'solves my problem well' is a pretty good substitute.
