From what I can gather the ACC's are a little tougher because of the carbon rap, but you can bend them.
Truth be known I doubt I shoot well enough to tell the difference
Yes they are a little tougher than aluminums, but again they can bend. I have seen it many times.
As far as telling the difference you can't tell much unless you shoot long range. I shoot Beman ICS hunters 400's and they are the same price as Easton XX75's. I can't tell the difference between these and other arrows unless I shoot a real long way. Even then I am not sure if I shoot well enough to tell the difference either.
