Verdict
The clearest difference is rating: Sound Amplifier at 4.6 against Megaphone's 2.8. Sound Amplifier also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). Megaphone's advantage is review sentiment (52% vs 34%) and device support (4 vs 2). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
