The short answer is "it depends."
Hogs are nasty, nasty animals, often infested with fleas and ticks. And the bigger they get, the nastier they are.
The only ones I have ever retrieved for eating are babies, they are delicious, if properly handled and prepared. I know hunters that have dressed sows, but I want no part in that. Their hide is tough, and cleaning them takes lots of time and patience - and south Texas can be miserably hot - so pick your times wisely if you anticipate taking meat home.
Also be aware that wild hogs are indistinguishable from farm raised, so lots of butchers cannot process them - or won't.
As with any animal, taste is largely a function of what the animal eats, and lots of hogs eat lots of nasty shit - sometimes literally.
Last part: game management programs for hogs say killing 70% of the population a few times a year will keep the population steady; taking fewer means population growth. I am an avid hunter, I try to be very responsible in my harvesting and respectful of the game. In that regard, fuck hogs, they are incredibly destructive and indiscriminate in their destruction. In general, hunters hate losing animals, but hogs represent a different rule set, at least in my estimation.
