Verdict
The clearest difference is rating: Undead Siege at 4.7 against Stack The Tower's 1.0. Undead Siege also leads on ratings volume (189 vs 1) and update cadence (fortnightly vs monthly). Stack The Tower's advantage is ads (none vs shown) and iOS requirement (7.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.
