What do you expect from the guy behind Preacher? Apart from Punisher, I wouldn't really consider that guy's take on a traditional comic character personally.
Eh, he's a bit OTT and I don't really like his whole attitude about comics in general, but he just "clicks" with certain characters. I tried reading the Boys, but after a few issues in, it became clear that it was just a way for him to trash cape titles and offer violence and ***. A great example of a vulgar, brash and awful human being done right and uniquely is Spider Jerusalem from Ellis' Transmetropolitan IMO. I've not gone through the whole thing, but so far, he's one hell of a fictional character, without falling victim to the usual tropes of the "anti-hero".
