Janeway because she is fiction, and most of my desires are directed at fiction. Kate Mulgrew because she's older than Janeway and I do appreciate older women. Really I think they are both beautiful, dynamic, nuanced people and the more you see of KM the more you realize how much of herself she put into the character.
(As an example of my preference for fiction, I am pretty much in love with NuSpock but I have no real interest in Quinto. I like characters. KM is one of the few exceptions and really the only actor I have that kind of adoration for.)
Who do YOU like? Oh and nice to see you around DA.
