Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for speed. When latency is the product, start here.
