The servers are all the same in the beginning but as you rank up in PUBG mobile, the player can notice that Asia’s server is the hardest until he gets above platinum then this title is passed to North America then to KRJP. So the most difficult server is definitely the KRJP server. There players are so good and have high RP. Besides, there is a lot of hackers. Asia server players prefer the snake game. While the opposite in North America players. South America’s players have good shooting skills and the Russians are also good but they are so selfish.
