>>103275490I liked GG's a bit more, she had a ton of original ideas with a lot of funny bits, I even laughed out loud at some parts. This was the most memorable and entertaining 3D I have ever seen. Only criticism I can give is that the Sims bit went a tiny bit too long and it was missing another solo Gigi performance.
CC's was also pretty good, it was a more traditional 3D compared to Gigi's, but there were a ton of guests, and I thought the group instruments performance was amazing, I also particularly liked that one song where she had a ballet-like dance. The negatives is that I didn't think the mario kart bit was all that interesting and it went a bit too long with not enough focus on CC herself. The debut in itself also didn't showcase CC's 3D model enough, which should be the main focus.
I can't comment on ERB's because I didn't watch it.
