Verdict
The clearest difference is rating: Devialet at 4.2 against Marshall Voice's 1.5. Devialet also leads on review sentiment (38% vs 11%) and ratings volume (3.2K vs 90). Marshall Voice's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (10.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.
