In my personal opinion and judging from the matches I've had on netplay with Zar(not that reliable since lag haet aoko but still) I think NAC is advantaged vs aoko. Prox orbs don't work, held orbs don't work for much except antiair, beams don't work, BE6A is picky about spacing, and 623 will often whiff, too. Aoko's movelist is more or less gutted VS NAC, can't say for vanilla neco since I can't play her for the life of me.
