Verdict
The clearest difference is rating: Moran Mobile at 4.2 against GZ Auctions's 3.7. Moran Mobile also leads on update cadence (every 6 months vs every 15 months) and ratings volume (12 vs 3). GZ Auctions'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.
