Verdict
The clearest difference is price: World Sun Time at Free against Airport Codes's $2.99. World Sun Time also leads on update cadence (fortnightly vs every 15 months). Airport Codes's advantage is chart position (#183 vs unranked) and iOS requirement (13.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
