Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Still early. Manus is more flexible for less money.
