I have used Claude Code in the terminal to the tune of ~20m tokens in the last month and I have very little to complain about. There are definitely quirks that are annoying (as all software has, including vs code or jetbrains IDEs) but broadly speaking it does what it says on the tin ime

I prefer using it via the terminal. Might be anchoring bias, but I have had issues with slash commands not registering and hooks not working in the plugin.
