Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier for creators training custom looks. B-tier for general use.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.
