Verdict
The clearest difference is ads: Contacts Sync at none against Cleaner's shown. Contacts Sync also leads on update cadence (every 5 days vs every 10 months) and ratings volume (15K vs 3). Cleaner's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 80%). On price, in-app purchases, monetization model and device support there is nothing between them.
