Verdict

The call

The clearest difference is ads: CalcZombie at none against Prison Tower's shown. CalcZombie also leads on iOS requirement (8.1 vs 13.0). Prison Tower's advantage is update cadence (every 4 months vs every 76 months). On price, in-app purchases and device support there is nothing between them.
