Verdict
The clearest difference is price: ESL assistant at Free against CAN Studio's $59.99. ESL assistant also leads on iOS requirement (12.0 vs 17.0). CAN Studio's advantage is update cadence (every 3 weeks vs every 4 months). On ads, in-app purchases and device support there is nothing between them.
