If you are choosing strictly between those two then I would say Battlefield 1, it's a year old so you could probably get it on sale as well. That being said, supporting EA right now is a really bad idea... So honestly you may want to go with the new Call of Duty, it's suppose to be pretty good. I am not sure what platforms you have, but some other games you could check out would be:

• Shadow of War, the lootboxes aren't that bad in it and you can play the game fine without buying a single one. Overall a really fun and entertaining game.
• Super Mario Odyssey is really great and an amazing (and well needed) new take on the Mario franchise.
• Evil Within 2 is really good if you are into horror games.
• Assassin's Creed Origins I have heard good things about.
• Wolfenstein 2 is pretty solid, but is suffering technical issues. Should be ironed out before Christmas though.

I'd avoid Destiny 2 because of the lack of content, pretty much everyone I know has quit playing it already out of boredom. Seems to be suffering the same issue vanilla Destiny 1 had, wait for some DLCs to freshen up the game first. Also, steer clear of Star Wars Battlefront 2 - there is a massive poop storm swirling around that one in full force.
