Verdict
The clearest difference is review sentiment: CZone at 100% against VRM's 40%. CZone also leads on rating (5.0 vs 3.4) and iOS requirement (8.0 vs 17.0). VRM's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (56 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
