While living in RSA, I hunted in Limpopo, Gauteng, Free State, Mpumalanga, and North West.
I have a serious Limpopo bias. I hunted in the Waterburg region near Bela Bela several times and loved the lay of the land and had tremendous luck when hunting. Limpopo is also great because you can leave Pretoria, hit the highway headed north, and be in the field in about 2 hours. You can shoot kudu, eland, impala, pigs, zebra and wildebeest in the morning and then do a walk up shoot on a wide variety of game birds in the afternoon. Plus, the weather there is nice as well. I never felt the urge or need to hit the road and drive way down to the to the EC when Limpopo was literally in my back yard. It is a great, great place to hunt.
Cheers,
