I have found that it's best to leave coding discussions like that to tools - we use Rubocop and Overcommit and it's a huge PITA every time it points out a minor quibble (we stop commits locally on our machines if new code doesn't pass both) BUT it saves us from having those conversations during code reviews. My general rule of thumb is that if there is a question of style that isn't caught by Rubocop, then it's very likely not worth having.

The other upside is that code reviews are higher quality and design focused.
