Vinland Saga vs Attack on Titan. Better written conclusion?
Note: This isn't meant to indirectly insult or undermine either conclusion. I personally loved both endings despite how controversial they are, and I'm simply curious to know which one you guys think is better written and why.
Vinland Saga: The story ends with Thorfinn's settlement falling apart as conflict and disease spread, with Einar and Styrk's deaths becoming the final turning point. Accepting that his dream had failed, Thorfinn decides to leave, but still leaves seeds behind for the Lnu before returning home to live peacefully with his family, having integrated lessons of his father figures, and his found families.
Attack on Titan: The story ends with Eren carrying out the Rumbling before Mikasa kills him, bringing an end to the Titans' power. His friends survive and work toward peace, but war eventually returns years later, showing that the cycle of conflict continues even after everything that happened.
Bonus question: Which one Arc ending did you like the most from each series, and why?
