How would you rank the Produce/Planet groups in terms of vocals and what vocal tiers would you give them?
My ranking (overall)
IOI> Wanna One> ZB1> IZ*ONE> X1> Kep1er
If I had to give their vocal lines tiers:
IOI
Sejeong - Above Average (B)
Yeonjung - High Average (C+)
Chungha - Weak-Average (D)
Wanna One
Jaehwan - Average to Above Average (B-)
Ong Seongwu - Average (C-)
Minhyun - High Weak-Average (D+)
Sungwoon - Mid Weak-Average (D)
Daehwi - Low Weak-Average (D-)
ZB1
Taerae - Average (C)
Zhang Hao - Average (C)
Sung Hanbin - High Weak-Average (D+)
Park Gunwook - High/Mid Weak-Average (D/ D+)
Ricky - Mid/Low Weak-Average (D-)
Matthew - Low Weak-Average (D-)
Jiwoong - Weak (E/E+)
IZ*ONE
Yuri - Average (C)
Yena - High Weak-Average (D+)
Eunbi - High/Mid Weak-Average (D+/D)
Chaewon - High Weak (E+)
Chaeyeon - Weak (E)
X1
Minhee - Was High Weak-Average in X1 but improved to A in Cravity (D+ to C+)
Seungwoo - High Weak-Average (D+)
Junho - Mid Weak-Average (D)
Seungyoon - Weak (E)
Yohan - Weak (E)
Kep1er
Chaehyun - Mid Average (C)
Youngeun - Weak (E)
The others are all underdeveloped (so F-tier). Even if more members supported overall, if one vocalist is clearly better than the main vocalists of other groups then I gave the edge to them (IOI vs Wanna One). On the flip side, if the main vocalists were on the same/similar level, I gave the edge to whichever group had more members with support (ZB1 VS IZ*ONE vs X1 Vs Kep1er)
