Verdict

The call

The clearest difference is review sentiment: Cortex Flex Performance at 100% against Edpuzzle's 13%. Cortex Flex Performance also leads on rating (5.0 vs 1.5) and update cadence (every 2 weeks vs every 4 months). Edpuzzle's advantage is in-app purchases (none vs 1) and ratings volume (166 vs 10). On price, ads, device support and iOS requirement there is nothing between them.
