hel with zealot question please

i was thinking about making a zealot but i dont know which kind to make these are my choices regular zealot >< or conc\beast zealot could someone that knows tell me the pros/cons of both or reccomend one please thx

Beast won't do any good in the long run since the fanatiscm aura it gives is only level 9, and concentrate sucks because of the loss of ar and ias, so I would say go with regular zealot.
