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.S-tier for teachers. If you teach K-12, start here this week.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
