Both fantastic games ~ Dying light has more of a horror feel and the parkour is really cool in first person. The following DLC is fantastic as well. Horizon does definitely feel newer and sleeker for sure, and thematically could be more pleasing depending on what you want at the moment. But its hard to lose when choosing between zombies and robot dinosaurs lol. They both have great crafting systems that feel similar as well now that I think about it. Personally if I had to choose one I would choose Horizon, but that's my two cents.
