It's hard to assess, especially from our position, which set of challenges the human soul prefers. But there's an interesting point to be made, touched in both "Civilized to Death: The Price of Progress"[0] as well as "The Dawn of Everything: A New History of Humanity"[1] that no 'savage' has been interested in non-coercively joining an 'advanced' society, whereas there are plenty of examples of 'civilized' people choosing the 'savage' life. I don't think the choice is as clear cut as it would superficially seem.

As is plainly evident, the vast majority of savages have chosen to incrementally create and join civilized societies. It’s a much larger challenge for an illiterate hunter gatherer to make a multi millennia jump into modern society than it is for someone to do the reverse.

This says nothing about their level of wellbeing.

Have they chosen? Or were they civilized?
