Correct me if am wrong, but isn't attacking the best form of pressing for a goal than defensive? This is I what think at least. I also prefer the attacking formation better than the defensive playing style, the earlier method make goals come through with a possible imminent win. But this also doesn't mean that defensive formation style is outdated or old fashioned because without defence, a disasterous loose is just waiting to happen especially if you're playing an opponent with very good attacking formation. So overall, i think both formation styles are of most importance in football because one helps maintain a trend and stop a possible loose while the other helps advance a trend and brings forth a possible win.
