Verdict
The clearest difference is in-app purchases: M at none against Expert Sign's 1. M also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.0). Expert Sign's advantage is update cadence (every 2 months vs every 16 months). On price, review sentiment and device support there is nothing between them.
