Verdict
The clearest difference is price: OneClock at Free against Flip Clock Pro's $2.99. OneClock also leads on review sentiment (83% vs 74%). Flip Clock Pro's advantage is rating (4.6 vs 3.9) and in-app purchases (none vs 2). On update cadence, ads, device support and iOS requirement there is nothing between them.
