Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier. Bet on this one — the Sparkpage format is genuinely new.
