Verdict

The call

The clearest difference is in-app purchases: Build at none against Alien Attack's 10. Build also leads on ads (none vs shown) and update cadence (every 3 days vs every 3 months). Alien Attack's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.5). On price there is nothing between them.
