Verdict

The call

The clearest difference is rating: edX online learning at 4.8 against Crimson's 4.1. edX online learning also leads on review sentiment (82% vs 43%) and ratings volume (11K vs 37). Crimson's advantage is in-app purchases (none vs 214) and update cadence (fortnightly vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.
