Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Best for teaching a kid to code in 2026.
