Verdict
The clearest difference is rating: HD at 4.3 against MIDI Drum's 3.7. HD also leads on in-app purchases (none vs 2) and iOS requirement (12.1 vs 14.0). MIDI Drum's advantage is update cadence (every 3 weeks vs every 19 months). On price, ratings volume, ads and device support there is nothing between them.
