Which do you prefer and why

i wouldnt say xxxholic was grounded it was just more of an almost "monster of the week" kind of manga, id lean more toward drama then anything no different then a nichijou in its everyday life just on a grander scale i would want a mix of both ie tokyo ghoul or fire punch (which happen to be my favorite manga) if your into the slice of life fantasies id seriously recommend The Girl From the Other Side it's sad, cute, slightly dramatic but not high energy and it has interesting, though atm minimal, world building https://images-na.ssl-images-amazon.com/images/I/91XY1nLj1XL.jpg
