There are lots of books I like very much that are in third person-- Harry Potter, anything by Stephen King; but the books that make me feel, that have me saying "You've GOT to read this!" are almost always in first person: Lamb's I Know This Much is True; Stewart's The Myth of You and Me; Foer's Everything is Illuminated; Memoirs of a Geisha; and several young adult books that have sucked me right in. First person is more personal; we're right in their brain, feeling it with them, and, when it's done well, there's an empathy with the protagonist that, for me, is tougher to acquire in third person.
Then there's verb tense, and while that is not the same animal as POV, it directly affects it for sure. I'm not a fan of present tense. It's disconcerting at first, and though I do acclimate as a book goes on (if it's good enough to keep me reading, see Hunger Games), it takes longer. Something about past tense gives an even more intimate look into things, because third or first person, you're seeing what they felt about what happened-- hindsight, baby.
So my ideal book to read is first person, past tense from a writer that knows how to wield a metaphor.
Meanwhile, I'm writing third person past and second guessing myself. First person feels more natural to me, but I didn't think it was the right voice for my WIP... though now I don't know.
Darn you, Doubt.
I guess this is what rewrites are for?
