i think too that ae ermor is slightly better .
you get lots of freespawns and lots of mound kings or censors .
sg gets "only" the shadow tribunes . they are cheap temple builders or can reanimate 1 shadow / turn .
the sg leaders are cool because they are immortal but for this they are quite expensive and in midgame you prefer bane lords / wraith lords anyway .
the main strenght of ae ermor is that they can build several raider armies with their freespawns/freespawnleaders which require still a respectable force to stop them .
because they are so huge in size they can deathpillage a conquered province in 1 turn .
while you can easy field 3-4 armies of 300-500 freespawn undeads midgame your enemy still needs about 10 priests with tough guards ( about 25-50 ) or 5 mages with tough guards who can holy pyre or wither bones .
fortunately ae ermor is thnx to swarming quite resistent to most sc's .
300 freespawns have quite a good chance to kill 1-2 scs with not too big losses .
unfortunately ermor has always a serious lack with deathgems and is only a mediocre clamhorder at best . so lategame you will have serious problems against especially arco , pythium , ryleh , caelum , tien chi if they were left alone long enough to start clamhording .
pythium because of communion and caelum because of flyby attacks is already earlygame nasty for ermor
