I find Cejudo far more annoying, though Joe B isn't really doing himself any favours either. Cejudo comes across to me as a really weak troll, but Benavidez keeps taking the bait hook line and sinker.
Cejudo just straight up saying "Oh hey man, you just lost two in a row" felt really lame, because it's not a clever jab or a cutting insult, it's just stating the obvious in a really annoying fashion. It seemed like Joe B didn't want any trash talk, but then was triggered hard by the stupidity of that sort of comment and then went off and made things even worse for himself.
