Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
