Well that depends. What do you plan to use it for?
I use Lapua brass in my 9.3x62, 6.5x55, 6.5 Grendel, 30-06 AI and believe it or not my 7.62 x 39.
I love this brass and I will continue to use it even though it costs more than Rem and Win. It is truly the best brass you can buy.
I would not pay the extra dime and use it in something like my AR-15. IMO, I don't think that the Lapua brass is going to show me any improvement in accuracy or longevity in my AR-15 over the less expensive Rem and Win brass.
Is it better? You Bet. Is it worth it? Yes, but not in every situation or rifle. If I were loading 223/5.56 from a bolt action target rifle, I would use it, for the AR not so much.
