In my experience, both Remington and Winchester brass is not what it used to be. The older stuff (pre-90s) is higher quality. Especially the WW Super and Super X.
Growing up Federal was the "cheap stuff". It's actually gotten a little better.
Hornady brass seems cheap, but actually has been holding up for me. However there is a huge range in case weights. In 270 win the spread is over 15 gr.
I think most people make a big deal about brass initial quality. The higher end stuff just seems to take less prep work, but if you put in the time, midrange brass like PPU, Starline, Nosler can all be made consistent. It just takes your time to uniform the primer pockets, deburr the flash holes, weight sort, trim, anneal, etc.
