Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
