Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
