Verdict
The clearest difference is in-app purchases: UPIICSA at none against Probability Distribution's 1. UPIICSA also leads on iOS requirement (12.0 vs 16.0). Probability Distribution's advantage is review sentiment (33% vs 0%) and update cadence (every 2 weeks vs every 5 weeks). On price, ads and device support there is nothing between them.
