Verdict
The clearest difference is in-app purchases: Challenge at none against Stack Champs's 8. Challenge also leads on ratings volume (32 vs 1) and iOS requirement (11.0 vs 15.0). Stack Champs's advantage is update cadence (fortnightly vs every 4 months) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.
