I mean Berserk does have pretty strong storytelling in its Golden Age arc and at least the character design and behavior feel in line with the world whereas Goblin Slayer has basically stereotypical comedy isekai characters get brutally killed and raped. It legit does not make sense how those characters in the first episode behave when, as the episode makes sure to tell, Goblins have been kidnapping and raping for a long time. It's drastically more gratuitous to Berserk because of all that.
Now you'll only hear me praise the 1997 TV adaptation of Berserk which features that arc. That has even trimmed some of the superfluous "monster of the week"-ish fight and makes it just the better. The Eclipse event is certainly disturbing and I'm not sure what to think of Casca's rape by Griffith, but the Eclipse also is a gruesome climax that had a lot of built up, after all.
The content that follows afterward in the manga, however, just gets progressively worse. Well paced storytelling takes a backseat to the monster of the week format. Torture and rape get featured so prominently that I certainly regard a lot of it as torture/rape porn at that point. Comedic relief characters and small little wizard girls join the party, which makes the argument I used above, about the character design etc. fitting the world, much weaker and there's even some romance in that. Oh and Casca, who I mostly deemed a pretty damn good character up until the Eclipse stays heavily mentally impaired for eternity.
I don't think the Golden Age arc, or at least its 1997 anime adaptation, should ever be put anywhere next to the instant-garbage that is Goblin Slayer. Comparisons to what the manga deteriorate into, however, seem completely apt.
