I found the YoRHa ending to be
to nobody's surprise pretty underwhelming. Final reward is just an orchestrion roll and the final quest is just one more confusing 'wat just happened' moment.

Unless there's shenanigans hidden away behind new game plus, which doesn't seem likely since they gave us ending E here instead of A, I think it's safe to call the Nier story a dud despite enjoying the raids gameplay wise.
