Verdict
The clearest difference is rating: World Clock Pro at 4.8 against Rect Clock's 3.7. World Clock Pro also leads on ads (none vs shown) and review sentiment (77% vs 59%). Rect Clock's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.
