Verdict
The clearest difference is ads: Gatefall at none against Alien Tower Defense's shown. Gatefall also leads on update cadence (every 2 days vs weekly). Alien Tower Defense's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
