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.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
