Verdict

The call

The clearest difference is in-app purchases: Amerigo 4 Flight at none against FAR/AIM's 1. Amerigo 4 Flight also leads on iOS requirement (11.0 vs 13.0). FAR/AIM's advantage is update cadence (fortnightly vs every 10 months). On price, ads and device support there is nothing between them.
