Hi Nora , welcome, head (& face) protection can be a very personal thing, part of which is dependent on playing style etc, ie are you a sniper or support gunner, the former often needs to look down a scope, which most full face masks restrict, the latter means you can often be a bit more casual with aiming style, more firing from a semi aim.
if your an assaulter, more running & gunning then you need to consider heat generation & probable misting depending on what eye pro is in use.
give us a bit more info on your style & requirements, hopefully, we can point you in the right direction.
