What's the worst Nightfall strike you've ever played? (Difficulty-wise)

For me, it has to be PsiOps Battleground: Moon. PsiOps, because of the amount of yellow bars, champions, and projectiles at just the beginning. Then, the champions, rank-and-file, and hive hunters during the ritual disruption phase. And, the final boss phases having champions ON TOP of Savathūn's Aspects. And to top it all off, darkness zones on all of those encounters.
