I don't see how brand of brass would change a lot about your preps.
You can still cull by thickness variance, and/or chamfer mouths, trim to same length, set primer pocket depths, maybe turn necks or set a false shoulder.
The brass will still have to be fireformed before it's capacity settles to match or not, regardless of sizing.
I use Norma, Lapua, Winchester(reloading brass), and am completely satisfied with each of them.
I've used Bell brass from Lazzeroni & Tubb, and found it to be horrible stuff.
But it didn't change anything about my preps. I just ended up with fewer cases actually used.
While most 'could' load & shoot pretty much any brass without preps -in a generous chamber. I wouldn't dispense with basic reloading over a change in brass brand.
I always expand new brass at the necks, no matter the brand. If you are neck turning, this is necessary anyhow. Otherwise, I see no need to size it. Agreed, it takes 2 or 3 loadings before it settles down.
I bought Lapua brass for my 6.5-284 Norma but was unable to get a FL die so I purchased a Redding neck size die. I neck sized this brass 4 times before I had to FL resize it.
Outstanding brass and outstanding accuracy. JohnnyK.
