Verdict
The clearest difference is price: JP at Free against Percussions's $2.99. JP also leads on update cadence (every 2 weeks vs every 17 months). Percussions's advantage is rating (3.0 vs 1.0) and ratings volume (3 vs 1). On ads, in-app purchases and device support there is nothing between them.
