Kai's verdict	S-tier. Market leader with reason. Start here for serious video.	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.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
