Kai's verdictS-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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Close second to Cursor. If $5/mo matters, start here.
