Crusher.
There's only one way I can think of to describe Pulaski.... McCoy-knockoff bitch.
That's how she started in her first episode, and (unlike some others) I honestly don't see how she changed at all throughout the season.
I think Crusher had more personality. She was kind, but she had her limits. She was warm, open, and comforting, but wouldn't take crap from anybody.
LOL that's pretty much how I would put it :P
For some reason Pulaski reminded me of a grumpy substitute teacher I once had.
