Setting to null is safer, as it allows GC to collect an object only after it becomes unreferenced from anywhere. If you, for example, dispose() a BitmapData which is still referenced, you will receive an exception. If you are absolutely sure that a certain object is not referenced from anywhere, for example, if the BitmapData in question is temporary, and there is only one reference to it, you can use dispose() to free memory. The best solution in case of rapid allocation/deallocation of temporary objects will be reserving memory for them and actually reusing them when you need to.
