Verdict
The clearest difference is in-app purchases: MasterKey at none against NFC Tag Manager's 1. MasterKey also leads on device support (3 vs 1) and iOS requirement (9.0 vs 18.0). NFC Tag Manager's advantage is update cadence (every 9 days vs every 3 weeks). On price and ads there is nothing between them.
