Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier. Market leader with reason. Start here for serious video.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
