'Demon Slayer' has some similarities. It has a world full of demons that the main character has to fight against, just like in 'Berserk' where there are all kinds of evil creatures. The main character in 'Demon Slayer', Tanjiro, is on a mission to avenge his family, which is comparable to Guts' own quest for revenge in some ways.
'Goblin Slayer' is also similar. It's a dark fantasy anime where the world is full of goblins that pose a significant threat. The title character, Goblin Slayer, has his own traumas and is very much like Guts in that he's a lone fighter taking on the dark forces. The overall tone of the story, being quite dark and violent, is reminiscent of 'Berserk'.
'Fate/Zero' can be considered too. It has a complex story with a lot of political intrigue and battles. Similar to 'Berserk', it has characters with their own ideals and goals. The battles in 'Fate/Zero' are intense and often have a high cost, much like the battles in 'Berserk' where the characters face not only physical but also psychological challenges.
