Verdict

The call

The clearest difference is in-app purchases: UHD A at none against Crash Course's 13. UHD A also leads on iOS requirement (13.0 vs 15.6). Crash Course's advantage is update cadence (every 4 months vs every 32 months) and ratings volume (1.6K vs 2). On price, rating, ads and device support there is nothing between them.
