From my limited experience with feral hogs in Georgia and Florida ---
The most important factor id what they have been eating. Hogs in good acorn years taste OK. If they are reduced to rooting in muck and eating carrion, they will be rank. Big boars are usually rank--they taste like a billy goat smells. The best are young pigs in good acorn years. I don't know how this translates to Texas hunting. If it were me, I would fill my coolers with little ones.
