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. The most interesting spreadsheet in years. Great for ops dashboards.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.
