Hi :) They are basically the same thing, in terms of game content. With collector's edition you get an exotic classe item (perk that help tour exp gains for relative subclass)+ dance emote specifico for class + shader for classe. (If digital copy) If you purchase a physical collector's you have other goodies ad a strange coin replica, a treasure island book and more. In my opinion... I would take the Collector's if physical. If not, it really isn't worth the price. (Should you need a veteran player for the "refer a friend" quest... Let me know ;) )
