The bioethics question of "should we" is an interesting intellectual exercise but in real life, of course we should bring back as many mega fauna as possible.
Biodiversity is the first reason that comes to mind; given the drastic rate of extinction of species, it should be an urgent priority to at least try to restore as many as possible. The more diversity in the animal and plant kingdoms, the more resilient the biosphere becomes.
What's more, it's likely that humans played a role in these animals' extinction, so it's only fitting that their descendants try to redress the situation.
Although the world has changed considerably since the Pleistocene and early Holocene (our current epoch), notably the recession of the last Ice Age, there are still parts of the planet that are suitable for cold-adapted mammals like woolly mammoths, woolly camels, and woolly rhinos.
I'm hoping someone can figure out how to revive Neanderthals, probably wiped out and/or absorbed by modern humans (possibly we ate a lot of them, actually). They had larger brains than modern humans and were much stronger. Possibly they would have a lot to contribute.
