Trip is rather humble(he accepts that he is weaker than certain people), and isn't exactly arrogant. He considers Ash weak and incompetent, but look at their actual fights? He has beaten Ash badly(thus he sees Ash as weak) and he has noticed Ash failed hard at noticing what his pokemon need to do(noticing Oshawott's closed eyes, telling Ash to train Focus Blast).
The big thing here is that Burgundy doesn't claim to be great. Georgia, while styling herself a dragon buster, lives up to that title(annihilating any dragon shown so far).
Iris brags about how great she is yet is not actually as great as she claims. Georgia doesn't claim to be better than she is. Georgia is also ready to accept that she is childish, while Iris completely considers herself above being childish.
Iris is easily less humble than either.
