I have only eaten meat from a couple dozen but everyone I ate tasted like it came from the grocery store. The biggest boar was 250lb from Texas. The meat was tough but tasted like store bought. Reminded me of moose. Moose tastes like a filet mignon but is about as tender as a truck tire. I ate meat from a 300lb sow that my brother killed that was tender and tasted no different from store bought. I have eaten numerous boars in the 150lb range that were tender and tasty. My understanding is that the meat can go bad very quickly. All the ones that I have eaten were killed in the winter and were gutted and stuck in a cooler within a few hours of being killed. I imagine if you kill a pig in the summer in TX, even at night, you would need to immediately gut it and put it on ice. Also, all of the pigs I have eaten were feeding on agriculture ie peanuts, winter wheat, and corn. I have never eaten a hog that was feeding on rotting animals or fish and killed in the summer.. All the pigs I have eaten were shared with others and everyone seemed to enjoy it.
I have noticed that the people who don't eat pigs are typically from Texas. I have said this before but it reminds me of people from Alaska that won't eat black bear. I have a buddy who lives outside anchorage who won't touch it. I have eaten meat from 2 spring bears from AK and a fall bear from Newfoundland. The meat was good from all of them. The fall bear was the best. I think it primarily fed on blueberries and garbage.
That being said, with the shortage of components and ammunition, my favorite caliber is whatever I can get my hands on. Right now it is 308 win because I can find it on the shelves.
