Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for realtime. If latency matters more than voice catalog, start here.
