Verdict

The call

The clearest difference is ads: Space Tower Defense at none against Trashbot's shown. Space Tower Defense also leads on update cadence (every 4 days vs every 10 months) and review sentiment (100% vs 75%). Trashbot's advantage is ratings volume (13 vs 2) and iOS requirement (15.6 vs 18.5). On price, in-app purchases, monetization model and device support there is nothing between them.
