Verdict
The clearest difference is review sentiment: KB at 79% against MIDI's 29%. KB also leads on rating (4.8 vs 4.1) and update cadence (every 4 months vs every 12 months). MIDI's advantage is price ($3.99 vs $14.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
