Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier infrastructure. The one platform every AI dev eventually uses.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for academic research. Nothing else comes close for systematic reviews.
