I think one of the best animes/game universes to be reincarnated in would be Pokemon.

Like the world seems overall pretty chill with things such as environmental destruction and poverty being fairly under control.

And even if a crisis happens, "regular people" never really notice them, because they tend to be solved before they become BIG problems.

Also, monster-girl spouses, possibly…

As somebody who hasn't been actually watching the series since 2010 or so, the world of Naruto seems like a terrible place to live. Ignoring the technology, the world is basically split between being ruled by feudal rulers and mercenary warlords. You had 3 "World Wars" in the span of a single lifetime, and casualties of these and other conflicts seem to be high, given how many child soldier orphans we have running around.

The Leaf Village recruits child soldiers under the age of 10, is full of bigots, has done its share of experiments on humans, has a powerful secret police force that answers only to a long-since appointed official, and is at least partially responsible for most of the major antagonists in the series… and somehow they're still the closest thing this setting has to good guys.
