Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier if you already pay Gemini. B-tier standalone.S-tier in the agent category. The first one I'd give to a non-technical friend.
