The initiations are very different, and the apes in terms of what they do outside of fighting are different, but it seemed more "fun" overall to me. Not necessarily fun to actually go through per se, but more interesting from a meta perspective imho.
In terms of them just being assholes? Eh... maybe? I like how they're done (so far) to be honest because it isn't quite that simple as they have layers. They do believe in having each other's backs too.
They just genuinely seem to have your back and be supportive of you even if they go about it in the most frat-bro-ish way possible. There's also the fact that so far, what are they doing to win exactly that could be considered wrong or being willing to do anything? That's the aspect in particular that seems no different from the Wolves outside of dialogue. We've been told, but not shown anything on that front. I mean there seems to be no performance enhancing drugs used, cheating, or anything like that.
Again, not knocking your view and can see your point... it's just for me personally, they're more "fun" from a player perspective. Maybe not so much if one had to actually go through that but even then, I dunno. Some of that could be considered fun lol. And everything they've done is Frat Light compared to the real stuff that one normally has to do to pledge... not that I support hazing.
