Is there something different about African Countries?

I have visited  only three African Countries and this includes my country of birth Zimbabwe, the country that I am currently residing, South Africa and the country I have recently visited,  Botswana.  Of these three countries I can rank South Africa much higher in terms of infrastracture, lifestyle but this highly depends on the area where you are residing. In terms of food, friendliness and humbleness of the people, I would say Botswana an Zimbabwe are almost at par.
