Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category leader. Nothing else is close yet.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
