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.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
