It's a bit unclear to me. I know I must compare references with is but pointers ?
Like Moritz said, there is no semantic difference with pointers, but you may consider comparing with is if you are looking for equivalence. It cannot ever be overridden, so if for some reason you decided to change your pointer to a class reference, it doesn't accidentally morph into a virtual call (possibly to a null object causing a segfault).
