As a teenager I liked Spock's angst, even though I had a life size poster of Kirk on the transporter pad on my bedroom door with the lip part worn out from over use.
I had a friend who was a huge Spock fan and even though we had no internet (because we were pathetically existing in the past, why Tom Paris idolizes such an era I have no idea) I knew that Spock was the hot one for all the tortured introverts out there.
Haha, that must be it; I'm a tortured introvert, so I was more attracted to Spock. I mean, I admit that Kirk was pretty, but I dunno, he just did nothing for me.
