Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier. If you're on Vercel/shadcn, this is cheating.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.
