I think I'm more on the reading side of the spectrum, since I wouldn't mind playing a completely linear VN at all and it would be more about the audiovisual experience for me.
When it comes to choices, I definitely agree with everyone here in terms of choices that should matter: if the choice is just meaningless, there's not much of a point to it. It's something that's frequent in mobile games, at most if you make a choice, you will get one or two lines of dialogue that are altered, but sometimes you don't even have that and the result is the same. Sometimes if you pick an option the game doesn't want you to pick, it'll even loop back into forcing you to pick the other option, and at that point it makes me kind of sit here like... "so what was the point?"
The amount of choices also matters to me. I like them when they are spaced out, since it makes them feel more impactful in the story, and I like using them as checkpoints in my playthrough. When they're too frequent they tend to stress me out more than anything because I immediately get in my min-maxxer mode and try to think about which choice would bring the most optimal result instead of thinking about the choice that feels right to me without caring about the meta aspect.
