Did you mean "normal" brass or Norma? You post asks about rem or win brass.
If you intended that to be Norma brass, in my experience it is good brass but soft. I use it for my 338 Khan (338/378 improved). It does not take much abuse to loosen primer pockets.
As for Lapua, they make great brass. Very consistent top quality stuff. It is also a fairly hard alloy and will stand up to top end loads much longer before the primer pockets go south. If it was available for all the calibers I load for I would use nothing else.
That said, I am not saying you cannot load good accurate ammo with "normal" brass. For me the answer to your question is...... if you are into precision loading and long range shooting, then YES it is worth the money.
