Kai's verdictS-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.B-tier. Still early. Manus is more flexible for less money.A-tier. Bet on this one — the Sparkpage format is genuinely new.
