Verdict
The clearest difference is in-app purchases: Database Design Basics at none against Machine Learning+'s 6. Database Design Basics also leads on update cadence (daily vs every 3 weeks) and iOS requirement (15.1 vs 17.0). Machine Learning+'s advantage is ads (none vs shown). On price and device support there is nothing between them.
