Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
