Verdict

The call

The clearest difference is price: X at Free against Ultimate Dragon Simulator's $0.99. X also leads on update cadence (fortnightly vs every 91 months) and ratings volume (25K vs 1.8K). Ultimate Dragon Simulator's advantage is rating (4.5 vs 4.0) and in-app purchases (none vs 11). On ads, monetization model and device support there is nothing between them.
