Kai's verdictA-tier. No reason not to use it if you're on Figma. Not worth switching for.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.
