Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for realtime. If latency matters more than voice catalog, start here.S-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.
