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).
