See, the way I envision this is that sex mainly works on a visual medium, since so much on it relies on feel and sight is the most sensitive part of our body. Simply reading about a hot chick getting railed just can't compare to an animated rendition of the same thing happening in 4K. Unless your story isn't primarily about sex and is only used as a means to tell a story, then I can't see why you wouldn't choose the 6-digit foundry over SH (unless you're looking for acquired taste, but that's why we have the Sad Panda).
As for murder, things get a little more nuanced. Violence isn't something as easy as visually representing it. Whereas sex can be just as enticing with cardboard cutout characters (for the most part) murder can do so much more with nuance and story. The reason why the average Saw film, filled with elaborate death traps and gore, can't match up to the intensity of that one scene in Joker where Arthur beats up two guys in an apartment.
Murder works best when there's weight behind it. Sex applies to that rule to, but not nearly as much as the effect that violence has. Mind that I'm referring both to their individual aspects alone, free of any context. Sex works as a standalone part (hence we got the Hub) but Murder requires at least SOME semblance of reason behind it, and sometimes, text delivers it better than visual medium, as they're able to convey mental states and emotions much better and more specific.
Which means Murderhobos have a MUCH BIGGER margin of error to fuck up in. Sex is okay, since all we're in for is watching an oversized frankfurter spray baby batter inside a soft clam. Murder doesn't have that privilege. There's only so many ways you could convey killing another guy, and it doesn't have the same natural, primitive, human pull as clapping cheeks and sucking pecs have.
So yeah, it's Murderhobos for me and it's not the fault of the genre. People are just terrible at creating context if all they want to do is show people getting murdered. They're just as equally bad in Sex, but the reality is that it's Sex. It's gonna be good, no matter what.
Unless your fetish borders beyond the average /b/ threads. Then I might need you to take a seat and hold these two crocodile clips to your nipples. Don't worry; it'll be fast.
