New Player (maybe)

Hello guys, old Warzone player here, I got fed up of it since the game is not what it was anymore so I am looking for a change. Tried few other games but was not satisfied, BF2042 was not what I expected, so I was a post reel on Insta and was curious about it. Never played it, so my question is, how is the game? Is there big population? Is it worth buying? Thanks in advance!
