Verdict
The clearest difference is review sentiment: Whirlwind Evolution at 75% against Rail Defence's 2%. Whirlwind Evolution also leads on rating (4.8 vs 4.1) and ratings volume (5.9K vs 894). Rail Defence's advantage is update cadence (fortnightly vs every 11 months) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
