Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for data teams. S-tier if you already live in SQL + Python.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.
