Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-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.
