Verdict

The call

The clearest difference is ads: Iron Saga at none against Block Den's shown. Iron Saga also leads on iOS requirement (12.0 vs 15.0). Block Den's advantage is update cadence (every 3 days vs every 5 weeks). On price, in-app purchases and device support there is nothing between them.
