Verdict

The call

The clearest difference is in-app purchases: Baselproblem at none against Data Structures and Algorithms's 1. Baselproblem also leads on iOS requirement (15.0 vs 17.0). Data Structures and Algorithms's advantage is update cadence (every 10 days vs every 11 months). On price, ads and device support there is nothing between them.
