Verdict
The clearest difference is review sentiment: When at 90% against M2E's 0%. When also leads on update cadence (weekly vs every 69 months). M2E's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
