Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for model-shopping. I use this for every prototype before committing.
