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.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Still early. Manus is more flexible for less money.
