I’m very happy with Hornady’s Creedmoor brass. It has been durable and extremely consistent. I’ve used exactly 10 pieces of Lapua’s Creedmoor brass, for a fun-test. All I can really tell you is I won’t use it with at least certain powders due to ignition issues. I have a box of Norma Creedmoor brass I’ve used just a little. It also seems fine, but no better than the Hornady; maybe not quite as good (consistent). Haven’t had any Nosler-stamped Creedmoor brass that I can recall.
Since you mention punched flash holes: Is there anyone who makes Creedmoor brass with drilled flash holes? I doubt it
