These are my own opinions so please don’t get mad at me! :) I'll be ranking vocals, rapping, dancing, visuals, and bias.
vocal:
BTS
1 jungkook, i think that needs no explanation. he suits the main vocalist position very well. :)
2 jimin, he also fits the lead vocalist. he’s my ultimate bias so i don’t know if i’m being biased lol, but i prefer his voice over any other voice :)
3 seokjin, he has such a great vocal technique and he’s so underrated! :(
4 taehyung, he’s just as good of a vocalist as seokjin, i just prefer seokjins voice over taehyungs.
5 hoseok, he doesn’t get the chance to sing a lot in BTS songs, but when he does he could easily be a regular vocalist.
6 namjoon, again, he’s part of the rap line so we can’t hear him sing often. but when he does he sounds really good for someone without a lot of vocal training :)
7 yoongi, he’s a great vocalist, but like namjoon and hoseok, he barely sings, but in seesaw he proved that he could definitely sing!
TWICE
1 jihyo, i love jihyo’s voice, and i think it’s a really powerful voice that can hit high notes very good.
2 jeongyeon, just like jihyo, she can hit high notes very well. she also hits low notes pretty good.
3 nayeon, she has a great voice, but i'm not in love with it.
4 chaeyoung, she's such an underrated vocalist and i think she deserves more lines.:(
5 mina, tzuyu, sana and dahyun, they have very nice voices and especially dahyun needs to sing more, she has the voice of an angel :(
6 momo, she had a great voice in sixteen, but it sound kinda forced and nasally when she sings live.
BLACKPINK
1 jisoo, her vocals are way stronger than rosé's, i'm no expert but i think we can all agree that jisoo sound better live. i don't love jisoo's voice but it's a unique voice and i think she should be the main vocalist.
2 jennie, her vocals are stronger than lisa and rosé's, but weaker than jisoo's if that makes sense. jennie has a very ordinary voice and no exeptional vocal range, but she sounds better than rosé when she sings (not raps) live.
3 rosé, as i said, i don think rosé sounds good while singing and dancing live, don't get me wrong, i understand that singing and dancing is very hard, and i can't do it better. but just like momo, her voice sounds very forced and not natural.
4 lisa, she barely sings, and she isn't that great of a singer.
rapping:
BTS
1 namjoon, this doesn't need explanation.
2 yoongi, he's a really good rapper and i love how he trows so much emotion in it when he raps.
3 hoseok, i love his rapping style, it's very different and refreshing, and it makes me feel much happier.
4 jungkook, he doesn't rap anymore, but when he did, he sounded so good!
5 taehyung, he's a rap line enthusiast and it's so adorable! he's pretty good at rapping as well.
6 jimin, he only really rapped once, but when he did it was pretty good for someone with littleto no rap training.
7 seokjin, i've never heard him rap, so i can't rank him off of anything. :)
TWICE
1 chaeyoung, she's such a good rapper and she deserves more lines!
2 dahyun, again, i think she's an amazing rapper and i think she needs way more lines!
3 momo, she doesn't really rap often, but she has a great voice for rapping.
4 the rest, i've never heard any of them seriously rap, i'm so sorry if i'm wrong!
BLACKPINK
1 lisa, i prefer lisa's rapping over jennie's rapping because she just sounds better to me, and i like her voice better. live lisa also sounds very stable.
2 jennie, she's a reallt talented rapper, but she doens appeal to be very stable when she sings live.
3 rosé adn jisoo, they aren't rappers and i've never really reard them rap.
dancing:
BTS
1 hoseok, he's one of the best dancers in kpop and i couldn't disagree.
2 jimin, also being called one of kpops best dancers, it's undeniable that he's really good at it!
3 jungkook, as the lead dancer, he's a really good dancer. he's really good at hip hop.
4 taehyung, some people say he's part of the dance line, and some disagree. he's a grest dancer, so idk why people don't lable him as one.
5 yoongi, i barely hear people talking about his dance, but if i didn't know bts, i would've thought he was a proffesional dancer.
6 namjoon and seokjin,they're nor the best dancers, but certanly not bad dancers! they're just a bit stiff.
TWICE
1 momo, i don't think this needs explanation. :)
2 mina, she's the main dancer for a reason, and when she did that ballet choreography in sixteen i melted!!
3 nayeon, her dancing looks so effortless and really smooth.
4 sana, i love her dancing and she looks really cute while doing it!
5 dahyun, i love her expressions on stage and her stage presence in general, and her dancing is so much better than that everyone says it is.
6 jihyo, i prefer her dancing over tzuyu's dancing because she seems more exited to me.
7 tzuyu, i don't love tuzyu's ufaces on stage, she looks kinda vanilla to me.
8 chaeyoung, her dancing is definitely not the worst in the group, the only reason why i ranked her this low is because the others are just so good at it.
9 jeongyeon, she looks kinda stiff on stage, but she isn't bad!
BLACKPINK
1 lisa, she's such a great dancer and everyone knows it!
2 rosé, i love rosé's dancing, it looks very smooth.
3 jisoo, i prefer jisoo's dancing over jennie's for many reasons, one of them being on stage.
4 jennie, let's just say that i don't like jennie's dancing. definitely not on stage, she isn a bad dancer, she just isn't my favourite dancer.
