Pressed meat cant be much better than restructured meat because the meat is no longer intact. Restructured meat means meat pieces that have been glued together with protein glue. The main problem with that is the risk of bacterial contamination. If you have intact meat, a single piece, you always have some bacteria on the outside. Since the outside of the meat gets cooked and the bacteria killed in the process even if you don't cook the meat all the way through, this is not a problem. But with restructured meat you may have a considerable bacterial load between undercooked meat pieces. The bacteria may not be killed off and there is an increased risk of food poisoning. The same issue occurs with chemically and mechanically tenderized meat, and ground meat. Intact meat, a solid single piece of meat, is much safer. I do eat burgers but only well done.
