Hmm. We just did this topic a few months ago. Love the votes for Crusher because "she's hot".
Crusher as a character was bland and boring. McFadden as an actress is bland and boring.
Pulaski may be a copy of McCoy but then again McCoy wasn't the only "cranky" character the world has ever known. One could even say that DeForest was playing a copy of a cranky police pathologist when he played McCoy.
I'll take Pulaski over Crusher any day. But then that's because I base my preference on character, not on who may or may not be hot.
