TFA offers simplistic, at times realistic, and very customizable (both on weapons and settings in general) capabilities. CW2.0 offers less setting customization but is so fine-tuned to perfection on realism, however, a lot of the add-ons on the workshop seem low-effort and rushed.
I really don't know, but for the time being, I'm going for the minority vote and I'm going to say TFA. Each update brings better visuals, better gunplay, and so on. The added animated viewbob and sway, the AT add-ons, it's all great for me. Like a simple yet realistic interpretation of CW2.0.
