IRyS's 3D showcase probably got a decent amount of views from mermaidrys and other fanservice which then helped sustain it in the algo
IRyS's bday otoh was a fairly by-the-books 3D live with top-notch singing
As opposed to Bae's bday which featured an orisong and album announcement, custom animations, a message from a famous VA, and was apparently the culmination of 2 years of work, all of which also led to a lot more comments
