Per SAAMI one operates at 62,000 psi (Creedmoor), the other at 51,000 psi. That’s the real difference, especially if you do not handload.
You get new barrels for your Creed more often.
We're talking about guns with 1200-1500 round accurate barrel lives assuming a CM barrel, more if you chase the lands a bit.
Now, with say an average of 5 rounds per hunt and maybe 200 rounds of load development at the beginning if you're really thorough, that works out to 200+ hunts.
The reality is there's very few people who go on 200 big game hunts in their life. Those that do can afford a rebarrel.
