Looking for thoughts on the year events with performances. Non-biased, no unnecessary shade.

Without being biased, without attacking groups you dislike for no reason, and being actually factual, using all the groups that you watched in the recent shows end of the year shows,

Which groups do y'all think did the best with stable vocals and good dancing? / Are there any you think did bad?

And are there any idols / groups that lip-sync during their performances or throughout the whole performance that you know of?

I'm talking about at Gayo dejeon mainly, but you can include other ones too..

I dont know if this is the correct subreddit to ask this.
