Don't know which Battlefield to choose (Battlefield V)

Hi all! I have never played a Battlefield. Played other games, and I was very attracted to the online MMO, single-player online shooter, team battles on smaller maps. Don't really like the emphasis on teamwork. I like just team Deathmatch, where the winner, who will shoot enemies.
I decided to try Battlefield, but faced with a choice. I read the reviews and see a lot of negativity about Battlefield 5. And if you choose Battlefield 4, online now to 2020 works for this game? Is it worth buying Battlefield 5?
