Why the coach picked it

You take creatine every day, so price per scoop is the number that matters. $42.99 for 90 scoops is about 48 cents each. $34.50 for about 60 is about 58 cents.
There's nothing else to compare in the scoop. Both labels list 5 g of creatine monohydrate and no other ingredients. Both are unflavored.
Both are on NSF's Certified for Sport database. If you get drug tested at a competition, or you just want to know the tub holds what the label says, that's the box to check.
Momentous says it runs its own tests for PFAS, heavy metals and microplastics on top of the NSF program. That's Momentous's claim, not NSF's, but it's on the product page.
If you won't run out and forget to reorder, Momentous's subscription drops the jar to $32.24.

When the other one is the right call

If you just want to try creatine before you commit, the Klean is $8.49 less up front. You'll pay more per scoop once you're taking it every day.
