Just finished this episode and just like the title says its recap.It doesn't show anything new and personally i can't say that i like it because its impossible to show 12 episode in less then 24 minutes(opening,ending).
There is no point in watching this if u already finished the main story anime.
And honestly only reason i can see in watching this recap is if u don't have time to complete main story but even then it still won't show you much,you'll get the picture of what happened but you will lose a lot of action and story and lets be honest:
We watch berserk because of its unique story and action
