I prefer Dr. Crusher over Dr. Pulaski because I think I let my self judge Pulaski per-maturly over the fact that she initially saw Data as just a machine. Over the season, she did grow on me.
Ultimately I prefer Crusher as she seems like a doctor that you would want helping you, compassionate and caring of the patient- Pulaski just seemed cold hearted. Bones on the other hand, that type of mentality seems more fitting for a man.
If we based all of our characters likability we would have a Star Trek with young adults that think mainly of sex and action... oh wait, we got that from Abram's already- look at how that turned out. Yuck!
