I've run these 2 bullets against each other ( .224 55gr) exact same case, primer, powder and load weight. Fired from the same rifle at the same target. Result was......winner the nosler varmegedon but difference was just slight. I find both these bullets to be extremely accurate in all guns they're shot in.
My results have been that your attention detail when loading is a bigger factor than the bullet choice when loading these 2 bullets. If you are trying to find the tightest groups. Consistency is the key... Ie all cases the exact same length, OAL exactly the same, all powder charges exactly the same etc. The less the variance in the manufacturing process the smaller your group become with either bullet
At least this has been my experience.
Bullets fired in
3 different savage axis's
Savage 11
Ruger American
Ruger American predator
Savage axis II
all guns shot 1" groups or less at 100yrds, some shot better than 3/4"
