I am very annoyed with Nika, base Luffy is fine, he always was a weird kinda guy, at least there are some funny scenes here and there. But the Looney Tunes style battles and Luffy loosing his last braincell as Nika is annoying af to me.
Overall all SHP can be annoying when Oda flanderizes them to the point when they become one dimensional. Yeah, I get it, Sanji is a simp, Nami is greedy, Usopp is a cowardly liar, etc., but when they still have their cool moments, I don't mind it that much.
If I still had to choose one, I would probably pick either Brook for his tasteless skeleton jokes or Ussop for continuous lying. Chopper is at least cute.
It could've been a poll thread btw.
