I found the gameplay different to bf4. There feels like there is so much aim assists, I find that i'm fighting against the autoaim when i'm trying to track a target. Also a lot of the guns are op, sniper rifles one shotting from 20 meters away, which basically let me quickscope 5 guys in a row, g17 c killing faster than assault rifles, m16a3 and m416 being more op versions of what they were in bf3 and cars killing you from touching the side of you when it has almost no speed.
I personally don't like the hotwire gamemode, the games finish to quickly and idk I preferred hiest.
The grappling hook and zipwire pickups around the map I really like, I had one instance where I was using the shotgun and there were 2 snipers across the road trying to snipe me so I ran into the building, went upstairs and got the zipeline, and went across the road on it and killed them both
The money system seems interesting but the menu GUI sucks and it takes ages to choose my loadout and switch class. So much faster in bf4
The gun models look cooler than bf4 and I like how you actually see the rail attachments like lasers and flashlights since in bf4 they always put them on the right side of your gun so you couldnt see it unless you sprinted. But I dont like how your character holds the gun when you havent fired for a littlebit, where it's on an angle, especially with sniperrifles where the scope covers the entire gun and you can't even see it unless you shoot
