My favorite animals are cheetahs. So I would like to see them in the natural habitats. Where should I travel to to maximize my chances?
According to this Wikimedia image you can find cheetahs around Africa and Middle East.

One of the easiest places to see Cheetahs (I saw a lot there) is Masai Mara National Park (Kenya).
If you are looking for one single place, go to the Okonjima Reserve in Namibia. It is located not far from the Waterberg plateau, a four hours drive from Windhoek.
In big reserves like Kruger (South Africa) or Etosha (Namibia) you can travel on your own. Nevertheless, I would rely on the services of a guide if I really wanted to see Cheetahs. Okay, you can find some on your own, it is perfectly possible. Moreover, a guide may fail to find some. That's nature ... However, using professional guidance is an excellent way to maximize your chances.
