Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier for designer-led sites. S-tier if animations matter.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
