Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier for ops automation. B-tier for simple copy (use Claude).S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
