Go for the highest difficulty you can get S-ranks at the boss regulary and very few to zero retreats in pre-boss nodes.

H / M seems to have best drop rates but the values can still change because of RNG.

E seems to have a lower drop rate of 秋月 and Casual ... I did not see any entry on poi-db for Akizuki at that level.

The best would be, if you can clear it and farm it on H-Mode at the same time, since you do not need to reset the Health bar of the boss every few times (and re-do all those pre-boss nodes with enableing boss-routing)
