Kai's verdictS-tier. Market leader with reason. Start here for serious video.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.A-tier for ops automation. B-tier for simple copy (use Claude).
