Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
