Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.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.A-tier. Bet on this one — the Sparkpage format is genuinely new.
