Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
