I liked
Bokura no Kiseki, but it is reverse reincarnation isekai type
The rest is just so-so to me
the
knight wife is quite enjoyable (until a certain point), even the
copy/lookalike is surprisingly enjoyable to me,
and I read them every now and then
Saint in japan is really a slowburn, and then it turned into ghost hunting last time I read
there's also that slice of life slave reverse isekai if you like that kind of story
(n.b., I'm not including the "dungeon appeared in real life" story like that [Boku no Heya] in here)
