Verdict
The clearest difference is review sentiment: Theremini Advanced Software Editor at 60% against MidiQuestEssentialsi's 0%. Theremini Advanced Software Editor also leads on rating (3.8 vs 1.0) and in-app purchases (none vs 10). MidiQuestEssentialsi's advantage is update cadence (every 5 weeks vs every 4 months). On price, ads, monetization model and device support there is nothing between them.
