Personally I believe that good isekai is an isekai that doesn't use too much predictable cliche, have a really good plot and the decision making of the character makes sense (as in an x happen because of y, not because the writer said so), it also need to have an actual character that you can actually remember too with its personality, especially the MC because most of isekai MC is a self-insert-op-harem MC
The strangest thing is, a good isekai should be the one that can remove the isekai part and it's still really good on its own as a fantasy Manga without the isekai thingy, a good example would be Genjitsu Shugi Yuusha no Oukoku Saikenki where it would then be a good story about a newly inherited King
I also enjoy an isekai that wear the trope and cliche proudly while being self aware of how dumb it is and put its own spin, the best Manga that pull this would be Kage no Jitsuryokusha ni Naritakute
Thank you for the recommendation BTW, it helps, especially during this trying time
