Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-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 for open-source model APIs. The default in this space.
