Verdict
The clearest difference is rating: Air Synth at 5.0 against Theremin Touch's 4.0. Air Synth also leads on price ($1.99 vs $2.99). Theremin Touch's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (15 vs 1). On ads, in-app purchases and monetization model there is nothing between them.
