I use them both and like them both. The Nosler brass demands the extra $ because of the extra prep work that goes into it.You use it, so you already know they come weight sorted, flash holes deburred,trimmed to length,chamferedand so forth. So, you'll have to decide whether having these things done byNosler is worth the extra $. If you have plenty of time on your hand and don't mind doing them yourself, then I'd say Lapua is the way to go. If you're like me, however, and don't have the time or inclination to do them, then Nosler may be the best choice. The last two batches of brass I bought (7mm RM and 300 WM) were both Nosler.
