Pork is fat and the fattest of all the hogs.
On the grill, with only salt, pepper and herbs (Jeezz, no ketchup or mustard) I just tasted pork and wild boar. I can affirm wild boar is excellent and lean.
Concerning wart hog and bush-pig, the francophone black cooks put their reputation at stake in cooking these meats with academic sauces. Then it’s not simple to judge how they taste.
Nonetheless I tasted wart hog and bush-pig skewers (kebab) : they taste the same. Nice meager pork with less odour than wild hog.

Damn, don't wolf bush-pig snout, it could have non-descript or crappy odor
