In theory strings may even be faster because the are compared byte by byte. If the first byte is already diffrent, further comparing will be skipped, while comparing two 32bit variables may take longer (thank comparing two bytes).
But of course, this is only a theory. As shambler said, as long as you check only a couple of strings per frame, it's not worth the troubles.
