Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier infrastructure. The one platform every AI dev eventually uses.
