No preferences but they're all patchers so theoretically everything plays good. If you want the maximum content, you should install RevisedBattles #15 before AzenMOD - so you'll have RevisedBattles' Battle Liches & AzenMod's Crypt Lich & Mummy entourage. (and you'll be one sadist little mofo )
Installing RevBattles after AzenMOD will not install any of the RevBattles content.
Hanna will add her custom Lich Guardian with no conflicts with either of those
