Verdict
The clearest difference is ratings volume: MARVLS at 35 against Pic2Mag's 1. MARVLS also leads on update cadence (every 8 months vs every 31 months). Pic2Mag's advantage is rating (5.0 vs 4.8) and iOS requirement (8.0 vs 11.0). On price, ads, in-app purchases and monetization model there is nothing between them.
