IIRC, isEqual: compares memory addresses, whereas isEqualTo: compares hashes of the objects being compared. I also believe that isEqual: is the preferred method.

isEqual: does not compare addresses. That's what == is for. Two distinct arrays with the same elements are "equal". You use isEqual: to test for that.

isEqualTo: is purely a synonym.
