95% of novels I prefer told from a 3rd person deep POV because I like character-driven stories. 3rd omniscient steps up for epic adventures, but too often I feel that deliberate wall between me and the narrator. Choose Your Own Adventure novels totally need to be written in 2nd. I haven't tried RPG Lit yet, but I suspect those also lend themselves to 2nd.
1st Person--if done well--can be delightful, particularly in horror and thrillers, but it takes me longer to sink into the story. The two genres I can't--just can't--abide in 1st are Romance and Erotica. Makes me feel like I'm reading a phone sex script or having a TMI conversation with a creepy couple. That's not to knock the authors who write Romance & Erotica in 1st; there are a lot of readers who like R&E in 1st. I'm just not one of them.
If you're writing in 1st, I penned a cautionary post a few years ago about When the Kaiyaiing Beast Takes Over Your Writing.
Now, if you thought I was going to chat about multiple POVs (multiple characters) telling the story, well, I've got a post for that too: So Close To Perfection...If I Was A Hydra. TL;DR: I will wall bang a book at page 2 if there's head-hopping (changing which character is telling what part of the story without clear transition such as a scene or chapter break).
