Since 'good' is a rather undefined post, lets make it more simple. Imagine you're an indie villager and your province is about to be conquered. You'd prefer your new masters to be...
(choose a nation).
I think most nations will be ruled out because they either make you a slave, sacrifice you, kill you just to make room for their offspring, eat you or make you a zombie. Some nations certainly feel 'acceptable' though, many others seem better than most. For example, LA Vanheim seems better than LA Mictlan, and Man is always preferable to Marignon.
