I actually did the same, and preferred Star Trek.
I found myself yawning in Ironman (and that was the one I was most looking forward to). I remember thinking, "If someone asks me about Ironman in the next few weeks, I don't think I will remember anything particularly special."
I'm not a Trekkie by any means (this one was hubby's choice), but I was more engaged with the story and I enjoyed it as a whole more than I thought I would. It might have been a more personal thing, though, as I haven't seen a Star Trek movie (or TV show) in many years, so remembering/seeing key characters reminded me of my childhood, when I had old Star Trek storybook records ... and I think Zachary Quinto is flawless as Spock.
I haven't analyzed them much beyond that, but that's my take. ....
