Verdict
The clearest difference is ads: Watcher Chronicles at none against Only One's shown. Watcher Chronicles also leads on update cadence (every 3 days vs weekly). Only One's advantage is rating (4.7 vs 4.3) and review sentiment (88% vs 64%). On price, in-app purchases, monetization model and device support there is nothing between them.
