Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
