I am perfectly happy in either. I enjoy first person because you can go deeper into the emotional recesses of a character and really feel what they feel, but you are limited to tell the story through only their knowledge of events. Third person is great for huge sprawling things set in alternate realities that require a lot of exposition.
I enjoy writing things that have more than one narrator (I'm working on one novel that has ten or so) and sticking in first person for them all to get an in depth look at each character. It also allows me to show how they each interpret different events. Everyone's truth is different.
