Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
