The class method new is the same as alloc/init although by implementation, it may be faster if the class doesn't need to pass a placeholder object from alloc—some classes do that. The class method array is much like alloc/init/autorelease in the MRC days although it may coalesce things, but that's an implementation detail you as a user shouldn't be too concerned about.
The biggest cause for concern is if you're writing this code in MRC vs ARC since you'd have to manage these memory points yourself.
