Bookworm is probably one of my favorites in terms of worldbuilding. The MC is very much a gremlin, only caring about her own goal but slowly learns to see the world, appreciate what she's got(her family) and coping with her limitations. She's probably my all time favorite in the genre.

Overlord I love also, I prefer to see the other POV characters, the ones not overpowered and then see these godly beings fuck shit up. Was especially fun in the men in the kingdom arc and later on holy kingdom arc.
