Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier. Market leader with reason. Start here for serious video.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
