Part of me wants to see an isekai where the MC is the antithesis of a doormat and has something that they will stand for and willingly die for no matter what comes their way
Isekai Putin (The Ride-On King)
Dude just wants to ride new and exotic animals and he'll stop at nothing to get his way.
Mushoku Tensei ~Isekai Ittara Honki Dasu~
Character development is good, MC tries to become a better person after his first life of being trash.
Saihate no Paladin
Would barely consider it to be an isekai.

Id: The Greatest Fusion Fantasy
I haven't read id in awhile though so I'm probably rose-tinted glassing the thing, it's pretty much mostly standard fantasy, if you skipped the first 2 chapters you probably wouldn't even know it was an isekai (it's not a modern day Japanese man to fantasy isekai though), besides, the story is never going to be finished because the publisher shut down and the rights to the work is probably up in the air. Author stated years ago that they might finish it one day but it doesn't seem like that's ever going to happen.
