In my opinion, I perceive the pre-maninated meats as covering something up.
They may just be normal cuts with whatever concoction the pack it in, but with my experience in the food industry; a marinade could hide a multitude of sins...
Bad tougher cuts, off flavors, meat nearing the end of usable shelf life repackaged, who knows.... They also raise the price and charge the same price per pound for the liquid it bathes in.
If I cook marinaded meat, I prefer to prepare it myself, I control the quality of the meat, the amount of salt, and most of all the flavors.
Nothing stops you from continuing to purchase these, but once you try making your own you will see a difference in taste and quality and will never want anything else.
