Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for aesthetics. If you care how it looks more than how it's made, this wins.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
