Verdict

The call

The clearest difference is ads: Zombie Infinity at none against Retro's shown. Zombie Infinity also leads on ratings volume (128 vs 5) and iOS requirement (13.0 vs 15.0). Retro's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 83%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Zombie Infinity sells 21 one-off in-app purchases and Retro sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
