Well, on the one hand, the original has two of my biases and one of my favorite vocalists from the group, and seems especially suited for 1/3 members. On the other hand, 2.0 has my co-ult bias, who is also another favorite vocalist, I've also had a whole new appreciation for Choerry's vocals since Loona Studio, and it's nice to see members from all three subunits performing together.
So I guess this is another vote for the OT12 version.
