Kai's verdictA-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier for speed. When latency is the product, start here.
