Verdict
The clearest difference is in-app purchases: Gravity Hero 3D at none against AI TD's 7. Gravity Hero 3D also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.0). AI TD's advantage is update cadence (fortnightly vs every 5 weeks). On price and device support there is nothing between them.
