It is funny to react to. I wasn't responding to anyone here in the comment section, but to Kadota. . .
Anyway, the subtle difference is pretty obvious to us, but I guess that for the characters in-universe: if Yugami = annoying, and Nidou = annoying, then Yugami = Nidou, while throwing out all other qualities.
Case in point: Kadota uses Yugami's image (without permission) for "poster(s) filled with bullshit" but Yugami is impressed instead of annoyed or insulted. In another scene, Nidou is shown to be self-absorbed because he doesn't like being called "you" despite being the second person in a 2-person conversation.
Edit: word choice
