solace

For me, the primary priority is always getting the heroine I want.  Everything else is secondary.  Otherwise, I use a mix of roleplaying and my own discretion to make choices.
 
School Days is an example of a choice system I really liked.  They're "grey" choices in a lot of respects that don't really fit any of your categories.  Any given choice could have moral, character connection, and strategic elements to it.  On one hand, you want to favor the girl you have your heart set on.  On the other hand, doing so might be morally problematic (it seems like a jerk move).  On top of that, one of the choices might appear to lead to a better outcome.  And on top of THAT, Makoto's fancy seems to seesaw back and forth from girl to girl in a very human way as events transpire and he becomes closer to or estranged from one girl or the other, and as a roleplayer I allowed that to influence my decisions.  It's a really beautiful system.

I'm actually mildly autistic myself, and I have friends who have high functioning Autism as well.  Interacting with them is refreshing because you know they'll always tell you what's on their mind, even if the truth is inconvenient.  That's a strength, not a weakness.  Autistics are often extremely honest with a strong sense of integrity.
 
Autistics tend to be nonconformists.  From their perspective, it's "neurotypicals" who end up seeming same-ish.

I'm going to read it. (｡≖ิ‿≖ิ)

I played Juniper's knot on iPad, too, and when people want to try a VN on iOS I'll usually send them first to Planetarian and then to J.K. I really enjoyed it for similar reasons to FinalChaos. Great experience.

I'm currently playing this VN, slowly. Sometimes, I just have to walk away from my laptop because I just can't stop laughing during the H scenes. So far it's cute, albeit it took me a while to get used to the concept of human looking dogs, and it took me an even longer time to get used to... well, I'll let you find out for yourselves.

That vndb link links to something else.

I've also noticed that you can differentiate VNs based on what sort of consequences your choices have. In some VNs nothing changes based on your choices (or very little, like whose H-scene you get at the end (looking at you, ML:U), in some VNs all of the changes are direct consequences of your choices (Katawa Shoujo is a good example, the only difference between the routes is who you spent/spend the most time with), and VNs where your choices affect which route you'll get, but not in a way that would make much sense outside of a VN environment (the first one that comes to mind is FS/N, pretty sure Shirou's actions aren't what cause Heavens Feel to happen instead of Unlimited Blade Works, though I may be mistaken).

It's a shame Dischan burnt out on Dysfunctional Systems 2, they were doing some good stuff in the OELVN scene.

Juniper's Knot is probably the only vn I read on my iPad and I liked a lot. It really shows how far characterisation can be taken even if only two characters are present. The presentation is also unique. It is quite a model as how short vns should be, it isn't rushed at all and feels complete.
