Goodlandia... yeah, that's what we're going with. Use all your evilitude to ruin these poor fella's day and establish yourself as the baddest of all the badasses in your corner of the fiery pit of hell. And if you think that doing that isn't evil enough, how about some corporate management abuse? Con your monsters into doing your work for you so you can sit back and reap the reward of their labor.

Verdict
The clearest difference is ads: Zombidle at none against Echo Planet's shown. Zombidle also leads on ratings volume (465 vs 23) and iOS requirement (8.0 vs 16.6). Echo Planet's advantage is update cadence (every 3 days vs every 3 weeks) and rating (4.9 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.
