Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier. Market leader with reason. Start here for serious video.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
