Verdict

The call

The clearest difference is monetization model: BLOCKJOCKS at free with in-app purchases against Master Anesthesia's subscription. Master Anesthesia's advantage is update cadence (every 6 days vs every 4 months) and ratings volume (2K vs 96). On price, rating, review sentiment and ads there is nothing between them.
