Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier if you already pay Gemini. B-tier standalone.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.
