For NCT 127, it's gonna sound crazy, but Jaehyun. He is a powerful and dynamic dancer and a great vocalist but people only talk about his looks and don't give him enough credit for his skills in these areas. I think he is unlucky because while he's a great dancer, 127 has better dancers in Taeyong and Mark, and while he's a great vocalist, 127 has better vocalists in Taeil and Doyoung and yet he's great!
Not only does he not get credit for his individual skills, but sometimes not for the role he plays in the group: there is a lot of NCT choreo where he and Yuta anchor or frame the work the mains are doing to create that NCT experience and within the vocal line his voice warms up and makes the vocal blend richer.
For NCT Dream, I think Chenle is underappreciated. He's one of the most stable and consistently reliable vocalists in NCT, a solid dancer, genuinely funny and charming and quite handsome in rl (I was surprised how much more good-looking he was in rl at KCON!) Because he doesn't have the "look" that's popular, I feel like he doesn't get the attention he deserves.
For WayV, I think YangYang is underappreciated. I love Kun but he has a loud and local contingent of us nuoyis hyping him and I think most recognize he's talented and multi-skilled. People may call YangYang out for being one of the best rappers, but they don't give him credit for his dance abilities or looks. He has a very striking, editorial look that SM doesn't always know how to capitalize on but when they do, it's amazing. Plus he has such a fun and charming personality.
