Pros:
Boots on the ground gameplay with much better weapon cosmetics and sounds.
A few neat added features and some nice killstreaks.
A lot of weapon customisation.
Better queuing for games in a new filter based queue.
Decent storyline with very controversial scenes, though reverting to a Cold War mentality.
Cross compatibility.
New map design.
Cons:
Little customisation with characters.
Operaters (characters) locked behind a paywall.
Weapons can be bought, giving unfair advantages.
Battle pass.
Bad matchmaking (balancing issues).
Latency issues, due to no independent servers. Makes shots be able to kill you around corners, through walls etc, depending on the oppositions connection.
Seems like there's aiming inconsistencies, with regards to controller aim assist. Seems like when you do bad, aim assist is spectacular. But when doing well the aim assist throws you off to the left, right, etc.
Maps aren't great, campers galore.
Lacking realism, with regards to aim speeds etc.
Overpowered and underpowered weapons (balancing issues).
Rubbish unlock progression, in multiplayer.
Tl;dr:
A decent game in general, but £60+ is a lot to pay for frustration and dissapointment.
Still pay to win / loot box mechanics, with an added battle pass.
No Nuketown.
