Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.B-tier. Still early. Manus is more flexible for less money.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
