Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier in its niche. The only one that actually gets emotion right.
