Crusher has the best bedside manner imo. They're all far better than any doctor I've ever seen in real life, so their skill levels should be close enough for my needs.
Now, Julian is the one I crush hardest on, and McCoy would make the best husband. Phlox would want to cure me by sticking alien worms up my butt or something, so no thanks.
Beverly would make me feel most comfortable and at ease.
