Kai's verdictA-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.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier in the agent category. The first one I'd give to a non-technical friend.
