Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. Market leader with reason.
