(English is not my native language) I choose 2B. there are too few fanfiction on "Nier", or at least I don't know them, so 2B.
in fact, maybe someone knows a good fanfiction on Nier or crossover?
honestly other than the godzilla one i like all of them but i prefer FOCs atm so i guess i'll wote 2B, but i would love to read all of them so it's up to whatever you feel like posting i guess.
