Kai's verdictB-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 content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. Best for teaching a kid to code in 2026.
