The call

The clearest difference is in-app purchases: LEGO® Builder at none against OneNada's 1. LEGO® Builder also leads on chart position (#89 vs unranked) and iOS requirement (15.1 vs 17.0). OneNada's advantage is update cadence (every 3 days vs every 3 weeks). On price, ads and device support there is nothing between them.
