Nijisanji's total watch-time was around 32 million hours.
Hololive's total watch-time was around 26 million hours.
Nijisanji EN's total watch-time was around 6 million hours.
Hololive EN's total watch-time was around 4 million hours.
Nijisanji of course dominates the Japanese market by a huge margin. Hololive meanwhile is getting a significant number of viewers in the Indonesian branch. however considering the impoverished state of Indonesia, it's dubious how valuable these viewers really are overall. Probably significantly lower value.
Another huge advantage Nijisanji has is a significant number of female fans, who donate MUCH more money than male fans do. Most of the top Nijisanji talents are male of course, and at least half of the fanbase is female. Unlike Hololive which has an overwhelmingly male fanbase.
