maxing level of amalgamation materials adds 3% to the end result of the amalgamation for each item amalgamated, so for the 4 stones, 9999*1.03 extra of all stats to the HUR material. maxing both HUR material will do the same.

Any time you want "the best" stats, then always max level all the cards. However, sometimes "the best" is not worth the time and resources. For non-LR cards (like these materials) it's worth it to max them as it's relatively easy to do these days if you treasure hunt regularly.
