I’m with some of the other folks around here: Pulaski was a better character. Conflict between the ship doctor and the captain makes for more interesting narrative opportunities, and Pulaski was great specifically because she was willing to stand up to Picard and be a pain in the ass.

Fans just didn’t like her because she didn’t immediately see Data as a person, but even that was interesting because not everyone would, and giving voice to that again created interesting ways to explore the implications of Data’s existence.
