I've not seen the pork shanks but if they are anything like the lamb shanks they should be good. I've always shied away from the frozen lamb shanks because I usually buy from our butcher and cook them from scratch but I've just had a long stay in hospital and OH has been fending for himself and although I'm now home I've very limited mobiliity etc. so he's cooking for me as well until I get stronger. Anyway, he tried them and thought they were good so that was one of the first meals he gave me and I have to admit I was surprised how good they are for the money. They are very tasty, lots of melt in the mouth meat and nice gravy. Good value imo.
