Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier. Category leader. Nothing else is close yet.
