Well, looks are about perception. Some will find him extraordinary and others the opposite.
When SOTY came out, I didn't think he was special at all, but then he grew on me. I like his personality off screen- quite steady, interesting and grounded. So, I don't think he is overrated, but maybe due to the dearth of good-looking men in the industry, he is hyped more than others.
Another point I'd like to make is that perception of looks has to do with how well they're doing at the moment. Nothing succeeds like success, so when someone is doing well, people like other things about them too. Halo Effect, as they call it.
I don't know why he makes statements that sound like word vomit, but I doubt he is full of himself. In fact, I think he is quite intent on making an impression and is not so sure of himself.
