Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Still early. Manus is more flexible for less money.
