PC Which one should I play, PUBG or Fortnite?

I've played both I personally prefer Fortnite, but it is all personal preference and your playstyle.

Fortnite is much more fast paced and invovles more than aiming. There is a heavy reliance on building which evolves the game sense of fortnite. Also I like the movement better in fortnite and feel like it is much more free and unrestricted though this is more of my personal opinion on the moving system. PUBG moving system is fine. I like the fact that I can easily loot without exposing myself from others for too long.

PUBG is slower paced compared to fortnite but heavily requires aiming and positioning. More people who like realistic games will play PUBG. And also people who like military sim's would enjoy PUBG because it's based off the arma 3 battle royale mod. Considering the person who created PUBG is the person who developed the arma 3 br mod.
