I have been reading up heavily on the NX8 2.5-20 vs the Mark 5 3.6-18x44. I have a 6.5 creedmoor (22") barrel and plan on a 13.5" .308 to compliment it.

Is that top end magnification not worth the eyebox trade off than say a ATACR 4-16x42?

Ugh. Its so hard to buy sight unseen. Anyone with any recommendations is greatly appreciated. Even if it's harsh. I know the 13.5" would benefit from more of a LVPO. Is it a fools errand to expect utilizing the 6.5 with the higher magnification?

I'm newish to long range shooting and just want to buy once / cry once. For reference: I have a Mark 4 2.5-8x36 on my mk12 clone and have had a lot of fun with that rifle and have found that glass to be satisfying.
