Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier infrastructure.
