Crusher gets points for writhing around on a bed have sex with the guy in the candle.
But Pulaski was far, far more interesting. We only hated her at the time because she saw Data as nothing more that a machine and we all liked Data. By the seasons end though she had warmed to him and it would have been interesting to see how that relationship would have played out over time.
Plus, she drank tea with Worf.
She seemed to have a crush on Worf and he didn't seem repulsed by it, quite the opposite.
But Crusher was hot with brains, so that trumps Pulaski.
