I personally prefer the middle of the road paths for most of these girls. Viola is one that I tend to lean more toward the vanilla path with though. I also like Gabby's vanilla path as well, but most of the others, I'm more in the middle. I can say that I'm not the biggest fan of the completely dark paths. Not my speed to be completely abusive. Establish a level of dominance, sure. Be an asshole for (mostly) no reason, nah. Then again, I'm not going to say that anyone who enjoys that content is wrong, but the dev did mention consequences to actions so can't really complain if things go a certain way in one path over the others. At least, that's my opinion.
