Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Best for teaching a kid to code in 2026.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
