flowerburgers, I agree with the multiple first-person. In my WIP I originally had four, then narrowed it down to two. It makes me mad when people blog about writing multiple-POV's and talk like it's always in third. They rarely acknowledge first-person-multiples. Is it a harder sell, I wonder?

(I couldn't quote your first post for some reason. It kept showing me your second.)

Back to the prompt. I think first person is easier with characterization because you have to be your character. It is also less confusing when you have a fight scene between two males or two females and have to constantly point out which "she" is the MC.
Third-person is also good. I think there are certain stories that require third person. Like if everyone dies at the end, or if there are eight different POVs.

I have written in both, but I personally like first.
