Verdict

The call

The clearest difference is price: Duck Game Bird Simulator at Free against Ultimate Bird Simulator's $0.99. Duck Game Bird Simulator also leads on update cadence (every 6 weeks vs every 81 months) and rating (4.4 vs 4.1). Ultimate Bird Simulator's advantage is ads (none vs shown) and chart position (#157 vs unranked). On ratings volume, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Duck Game Bird Simulator holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 1.6K and 855 respectively. Written reviews complicate that: 70% of Ultimate Bird Simulator's written reviews are positive against 58% of Duck Game Bird Simulator's, so the app with the better star average is not the one people write more warmly about.
