Verdict
The clearest difference is price: Midi Player at $0.99 against Lead Sheets XML's $9.99. Lead Sheets XML's advantage is update cadence (monthly vs every 27 months) and chart position (#170 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
