Verdict
The clearest difference is update cadence: Calendar Week at every 3 months against Watch Weeks's every 11 months. Watch Weeks's advantage is review sentiment (80% vs 67%) and iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
