Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.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.B-tier. Still early. Manus is more flexible for less money.
