Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
