Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Useful for first drafts. v0 is the better bet for shipping code.A-tier in its niche. The only one that actually gets emotion right.S-tier for realtime. If latency matters more than voice catalog, start here.
