If you don't reload, these are no better or worse than any other similarly mass produced surplus ammo. If you want to save the brass for reloading, stay away from them as they are part of the batch I was having great issues with decapping. In some cases the flash hole was undersized and others the flash hole was off center both of which lead to broken and bent decapping pins.
Which is "the good stuff"? What I have seen sold out of the store I worked at were made by RUAG and mostly came from Germany with some boxes marked Made in Hungary found at the range. I have heard of some ammunition being assembled in the U.S. out of Lake City brass but have not seen any in person that I know of. I have not seen anything of this line actually from Norma of Sweden other than the name on the boxes.
It would be nice to get actual Norma cases at the price this ammo sells for as that would be loaded ammo for less than the price of just the brass that comes in Norma boxes. That would be a great deal even if the ammo was no better than Winchester Green Tip.
