well, the advantages of having choices is that you can have various kinds of stories in the same novel. You can write a dark route, a light romance comedy, and a route made of fighting all at the same time.
With kinetic ones, if you don't like the story, that's it.
For example, I can't stand any kind of tsundere. This is personal, but whenever a tsundere appears I'm always thinking "oh god, please, someone just kill her".
If a kinetic novel has a tsundere that appears too much, I'll probably end up rage-quitting it and forget about said novel. It's a flaw of mine that already made me quit some awesome novels. Whereas if there was branching, I could just skip said route and keep enjoying it.
Branching is convenient, but I wouldn't say that it's needed.
