Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for creators training custom looks. B-tier for general use.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
