I think the most annoying contestant in Hell's Kitchen is Elise from season 9

That woman just keep talking. I don't mind if woman talks. But if you constantly talking pure hatred and jealousy and every sentence you say shows bad attitude, like you from da hood and you keepin it real in front of everybody, And if somebody doesn't agree with you, you threaten them with violence. hey, this bitch got a serious problem. Nobody in her team can tolerate her. Very annoying. The girl team suffered from communication because nobody dares to speak to Elise. Sometimes you say something which is not meant to insult anybody. But Elise could suddenly jump out of nowhere and threaten to kick your ass, because for some reason she thinks you are pointing at her. Wow. I don't see how anybody can work with a lunatic like Elise.
