Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier in its niche. The only one that actually gets emotion right.A-tier if you already pay Gemini. B-tier standalone.S-tier for model-shopping. I use this for every prototype before committing.
