Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier for model-shopping. I use this for every prototype before committing.A-tier if you already pay Gemini. B-tier standalone.
