Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.
