It is a good code viewer but way too heavy if you want to switch between branches often on a sufficiently large product.

VSCode for the rare time I need to view a file.

GitHub or Tuicr for code review. Still waiting for an agentic first review environment- which Jetbrains has missed the ball on.

You'll be surprised (or not) to find out a lot of people aren't using anything. Claude gets asked to build it, then some other clown uses their copy of Claude to do the PR review and then it gets merged.
