Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier in its niche. The only one that actually gets emotion right.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
