Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
