PUBG is a terrible implementation with textures and assets purchased off the unreal store. PUBG piggybacked off the popularity of H1Z1 and took off because it was slightly better. Fortnite, although cartoony, is by large and far the most stable and most competitive battle Royale out there. Epic's update pipeline and developer blogs are phenomenal, especially compared to Bluehole. PUBG performs worse in it's current state than when it did pre-release.
