I really haven't noticed a difference with frozen meat not tasting as good. The ground beef, we buy in the tubes, they're very well packaged, air-tight. And most everything else seems to be fine. We either keep the packaging from the store, or vacuum seal it with one of those little devices. If a meat came on a styrofoam tray with thin plastic over it, I'd probably try to use it quickly, because that's not the best packaging.

Where I really noticed a degradation of quality with frozen items was with frozen veggies and fruits. They got freezer burn REALLY quickly, surprisingly so.
