I bet if you tried some of the cow I buy from a local farmer, that's fed mostly grass, you'd think you'd died and gone to heaven. Not to mention it's more cost effective. There is a huge quality difference.
So comparing the two...steak that's been fed corn, crowded into pens, slaughtered, washed with ammonia, processed some more, sometimes even chemically dyed, shipped, and then on your plate versus a cow that was raised locally on a farm feed grass and hay, slaughtered, and handed over for me to cook, I'll take my steak over yours. :shrug:
I always like the commercials for California cows (though they aren't selling beef) I think it's true - a happy cow is a yummy cow.
Holds true for just about anything I guess.
