Verdict
The clearest difference is rating: COSM Events at 5.0 against Core's 3.0. COSM Events also leads on iOS requirement (10.0 vs 16.0). Core's advantage is ads (none vs shown) and update cadence (monthly vs every 3 months). On price, ratings volume, in-app purchases and device support there is nothing between them.
