Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for teaching a kid to code in 2026.
