Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
