Verdict
The clearest difference is update cadence: Clog at every 2 weeks against Calendar Notes's every 11 months. Clog also leads on monetization model (ad-supported vs free with in-app purchases) and iOS requirement (13.4 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.
