A good isekai: Isekai de nonbiri Iyashi Te hajimemasu, an isekai about a girl wanting to be a healer in another world. Plus the MC is cute.

Finally an isekai manga that isn't a bait and switch with a cute girl on the cover but the MC is some generic guy orz

It's shoujo though, which, if anything, probably means it's better than most isekai
