Of what I've watched, it's Dandadan and Frieren. If I have to pick a best one, it's the latter. Its fanservice is so subtle you won't notice if you are not aware.
I love how no one has said anything about Dandadan, because, of course it's Dandadan. If there's anything Dandadan is most definitely not, it's subtle.
Fun show, though, except when it chooses to traumatize the viewer for no apparent reason.
I think the OP thumbnail is the one that least suffered going from manga to anime, sadly anime is getting too censored even for Japan's late night tv, 2.5D seduction was a fumble according to my friend that reads it.
So unless it airs on cable or something like Ishizoku Reviewers we get stuff like Ayakashi Triangle and the Ranma 1/2 remake.
