Verdict
The clearest difference is in-app purchases: MusicSketch at none against Composer Pro's 4. MusicSketch also leads on review sentiment (94% vs 72%) and rating (4.7 vs 4.5). Composer Pro's advantage is ratings volume (697 vs 130) and iOS requirement (15.0 vs 26.6). On price, update cadence, ads and device support there is nothing between them.
