How would you compare life in South Africa to other southern African nations like Namibia and Botswana?

My presumption is that in Botswana, life is more stable and secure - crime is far less and it’s more relaxed, but opportunities are much much less than in ZA no? Same in Namibia, except Namibia is poorer than ZA unlike Botswana which has equal-ish wealth.

Is it that whilst South Africa is ultimately by far and away the richest country in Africa, Botswana offers a better life for its people? And what about Namibia, which many say is better as well. A common sentiment I hear from many Saffers is that Namibia is a literal copy of South Africa but better, is it true? How do these 3 compare?
