Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
