I mostly enjoy the novels of the "moege" variety, examples are: sabbat of the witch, fureraba, if my heart had wings, newton and the apple tree, saku saku, dracuriot.
While I consider the best vn's to be: Rewrite and The Fruit of Grisaia series.
This was an isekai? Wow I didn't know that it was until I read the comments. Well regarding the manga itself it was quite good for now, looking forward for more~
