Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier. Market leader with reason. Start here for serious video.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
