Verdict

The call

The clearest difference is rating: Space Tower Defense at 5.0 against Digger Machine's 4.5. Space Tower Defense also leads on ads (none vs shown) and update cadence (weekly vs every 3 months). Digger Machine's advantage is ratings volume (351 vs 2) and iOS requirement (13.0 vs 18.5). On price, in-app purchases, monetization model and device support there is nothing between them.
