bts black swan mr removed -
nct 127 punch mr removed -
Black swan has a complicated choreo and a lot of the moments would cause breath instability, but bts handled it well overall. RM has the most stable voice out of all the rappers, while suga has better flow while still maintaining stability and staying on key. jhope is stable when he gets his 0.1 seconds. jimin is on key most of the times, but some of his vocal slides sound bad and out of tune. jungkook's voice has gone a lot stronger but he falls flat on some notes (which is only natural with the dance) but he sounds good and stable most his lines. v is off key in the first verse but is strong in the first half of the chorus.i feel like he isn't as good as jungkook at holding vocals during crazy choreo. jin is a stable singer and his voice is clear. even tho his voice isn't as high as jimin's, he still hits his notes quite smoothly.
punch choreography isn't as hardcore as black swan but their vocals are more difficult, so kinda evens it out. nct 127 is mostly chanting/talking/rapping, but there are glimmers of vocals in there. in the intro, all the members are singing so you can't really tell who is going off key. they all sound pretty good in unison though. i can't hear taeyeong when he whispers but his rapping is good; nice flow and clear enunciation, just not loud enough. jaehyun has a stable voice that cuts through in the chorus but he goes a lil shaky at times. haechan is really stable and has no trouble hitting his notes, same with jungwoo. very impressive. taeil has a strong voice and hits his notes quite effortlessly. jaehyun is stable when he leads the chorus. doyoung is shaky in his first lines, but sings perfectly in the bridge. mark doesn't get much lines, but he raps clearly and enunciates even better than the korean members. . yuta's vocals in the chorus are stable and good. when the vocals go quit
i tried to choose songs that had a fair amount of singing vs rapping to compare
tldr; nct 127 are better performers imo
