Buck, his AR not so good but the DMR is so good Ash is just quick with a broken hit box, nothing else good about her
Buck cuz 1. SHOTGUN and 2. Good soft breacher
I would say Ash. Fast rushes with a small hitbox.
An operators worth depends entirely on how effective you are with them. An ash can have a similar effect as a buck if you run breaching charges. While you can’t open the roof above you except for your two breacher rounds, an ash might be better if you want to take advantage of rotates as you can move quicker. Buck has more opening power for floors and walls but since he lost his frags, sledge is better now. I run sledge shotgun so I still have the ability to open hatches and the roof.
I have to say Ash
I'd have to go for buck. Opening floors, hatches, making lines of sight, having grenades and quite powerful guns. He's also Canadian which is a plus.
Buck by far he can make lines of sight in any direction which makes him super versatile
In my opinion its ash
