I use Lapua and Norma for the 6mm and 6.5mm respectively (Norma has large primer pocket). The only difference I see is that the Norma seems a bit harder. Tried Peterson in 6.5 and 338LM, not really impressive, especially neck wall consistency, and had a case neck split after 2 firings (no other splitting through 8 firings). All Lake City for 5.56 rounds.
I run fairly heavy loads and anneal all cases after each firing. Usually toss cases after 15-20 firings, or when the pockets get too loose. Norma pockets seem to hold up longest.
Criteria for case selection: Availability, neck wall consistency, dry and wet weight consistency, primer pockets holding up
