I wanna say CSGO but idk it kinda went to shit and well everyone is playing PubG its still kinda rough in development but I would still say go PubG I guess.
cs:go is very smooth and balanced. pubg is just a different experience, not even the same objective. I have 2500 hours on csgo and around 300 on pubg and I cant really compare the two games
Pubg, its like golf, you have a bad game but ya keep going back for the torment of the game.. or it's like a drug, once you get a chicken dinner you are constantly chasing it
