Scientifically it may look different, but as a hunter in Africa you can distinguish between three groups of buffaloes; Sudan buffalo, Forest buffalo and Cape buffalo. The biggest representative of the group is the Cape buffalo, which also has the largest trophy, followed by the Sudan/Nile buffalo, which is slightly smaller and also has a different smaller horn shape, and finally the smallest of the group, in terms of body size as well as horns, the forest buffalo. I cannot write anything about the forest buffalo as I have never hunted one, let alone seen one. I have shot a few specimens of the other species in various countries of Africa. They all behave the same and are all hunted in the same way. It could be that the West African buffalo is a bit more active and you need more effort to track it, but maybe that's just a subjective feeling, because I shot more Sudan Buffaloes in West-Africa than Cape Buffalo in East and South-East Africa.
