Verdict

The call

The clearest difference is rating: DPI at 4.7 against Sky Rider Flight's 3.2. DPI also leads on review sentiment (60% vs 38%) and ratings volume (1.1K vs 66). Sky Rider Flight's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
