Here is my take on it. I use Lapua, ADG, Alpha and RWS wherever possible.
My quick example of cost savings is I bought 100 pieces of RWS 300 Win Mag brass that I used to reform into 7mm Mashburn Super in 2016, I have only done 50 of them, as I figured I would do the other 50 when I started wearing them out. As of right now, I have at least 12 firings on those original's and I am about to load them all again. I have had exactly one case that developed a split neck probably from not annealing it or it got skipped, but they were FF'ed back in the day with 4350 and a 140 grain bullet and have withstood ALOT of firings with RL33, Retumbo and now N570 with 175's between 3050 and 3100 over and over. Pockets are still tight as new and they just keep working. After the first firing I have to cut the donut out of the neck which is a pain in the butt, so the less I have to do of that, the better.
When I started with the Mashburn I was lucky to get 5 solid firings before pockets would open. To me, I saved money by not having to monkey around with the lesser expensive stuff up front cause I'd have likely be on my 3rd batch of Hornady or Nosler.
Not saying Hornady and Nosler are bad, cause they aren't, at all, they just don't last like Lapua or RWS or ADG does so it is a time and cost savings when and where the better brass is available. I still use WW, some RP, Hornady, etc. Works fine as well, just usually requires a bit more prep.
