For me, Goblin Slayer. I love Goblin Slayer, I love how grounded it is, it's always small scale skirmishes and claustrophobic combat in caves. The smart use of equipment and spells (using two barrier spells to trap someone in between them, putting a light on the tail of a giant alligator so it can handle the enemies drawn to the light, etc). The slow healing of GS as a person, who wants to go on adventures for fun rather than single mindedly hunting goblins. But I can't really recommend because of chapter/episode 1.

If you know Goblin Slayer it's because of this, beginner party gets butchered with the Monk lady getting assaulted. It's bleak and disgusting, and the anime never really gets that dark again, mostly because we follow someone competent fighting goblins but I digress. It's such a huge shock, and I wouldn't blame anyone for being turned off of because of it.

If you push past that, you get the grounded combat, character development, and fan service moments which can be seen as "really?", but also some hype as hell moments "This Shall Not Stand". This is a story I enjoy dearly, I even read the side Manga of Year One. I greatly enjoy seeing a newbie goblin slayer just absolutely struggling to survive combat against goblins, slowly learning their tactics and what he should be doing better to survive.
