Interesting points all around, folks. I don't know if there's any one style that I prefer over any other. However, I definitely have all 3rd person at the top of my favorites.
I think there's a little disconnect with 1st/2nd person, because it tries to pull you in and put you in the shoes of the character; what if I can't relate to the character? What if I don't want to think and do the things being narrated? *shrug*
I'm trying to come up with some books written in 1st/2nd person that I'd consider "great" and I can't do it. Either the genre is too difficult to write or readers just can't get attached to the perspective.
Most (pretty much all) of my work is in 3rd person. I made a few attempts, via short stories, to engage in 1st person... won't be trying that again anytime soon!
