It varies, but my current vsAI prefernces are:

-Proportions
-wp anywhere in system (easier for AI)
-all wp not connected (delay 1st contact even longer, so AIs will be more developped)
-players can start in same system (It happened to me and it's been a great game.)
-homeworlds not necessarily same size
-high events / high severity
-Max AI + max neutral. (neutrals are cool in proportions - they defend their homeworlds much more closely than regular AIs)
-Simultaneous (it's too easy when you have tactical combat)
