Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
