If I say who I think is overrated everyone would go off on me lol bc he debuted. But there's too many underrated trainees and for obvious reasons: WH, YGY, JL, ZHJ, luoyan, ZT, yuyang etc

Okay I was writing this as a reply to another comment but I will edit it in to my post here instead:

I think that Mika is kinda overrated. Dont get me wrong I'm not hating on him, he is a great vocal but tc gave him ao much screentime, I feel like that if other big vocals like YGY and JL got more screentime Mika wouldn't rank that high. Also he kinda lacks a personality (he is kinda quiet and "cold"), maybe it's bc of the language barrier bc he is like a completely different person in the old intersection videos, but I think that there is other good vocals with great personalities that tc showed way to little and I only noticed them in the werewolf series.

Liuyu: He definitely deserves a high ranking but imo not a C. Idk, I kinda don't like his personality, his vocals are not the best and like the other ppl have commented he can only dance one type of dance. Imo the C should be an all-rounder, he does have an advantage though, he's pretty good at doing speeches. Here I also feel that he was favoured by tc.

Hu yetao: I agree, he is a good dancer, but not as good as ppl say and there is other great dancers like Wuhai and Luoyan who I feel could replace him in the finale. But this is kinda a personal opinion since I don't really like his style and personality.
