Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier in its niche. The only one that actually gets emotion right.
