I am in the camp of using as little rubocop as possible, but still using it. I like it to address the drastic stuff like misalignments, mixed tabs and spaces, obvious sloppiness.[1] Still, it should allow most of the freedom. My preferences are posted in what I call a "narrative" Rails template[2]. It's a relaxed "standardrb", which I have since relaxed even further, but haven't updated the repo yet.
