Verdict
The clearest difference is rating: MMC Member App at 5.0 against Sotheby's's 3.4. MMC Member App also leads on ads (none vs shown) and monetization model (free vs ad-supported). Sotheby's's advantage is ratings volume (96 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.
