Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.S-tier for model-shopping. I use this for every prototype before committing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
