I would choose Battlefield V because I looked up the reviews on both of them and Battlefield V scored a 4 out 5 star and I read some of the reviews and it definitely sounded like the better game, and Anthem only scored a 2.5 out of 5 with some bad reviews..
I'd pick Battlefield V. I've enjoyed just about all the previous Battlefield games. Really like the multiplayer aspect to it. Especially smaller matches. Anthem looked promising. But I keep seeing negative things about it.
