Are they the least synchronised groups top groups?

They aren't a dance group, they are singers and they sing. They deliver great songs.

aespa isnt even a top group.

Only bp is a top group and they are particularly less synchronized than the rest

yes bp isn't really synchronised and from what I have noticed in their ususal performances, they focus on live vocals and hyping up the crowd more(except in cb music shows) rather than depending upon a hard synchronised choreo plus they are 4 members and they tend to use backup dancers only at their bridge part of the song which makes their stage look kinda empty sometimes. this is my personal observation.

exo too

Stop mentioning BP for clout. nmixx is a better comparison.

Why u mentioning exo here?exo have great choreography and dancers.

Cause Blackpink strengths is individuality, the best in kpop imo

it's a lot easier to notice mistakes and for groups to appear less synchronized if they have fewer members

clearly it's not hurting bp if they have hundreds of millions of views on performances and dance practices so why do you really care OP

Cause op asked if Aespa and BP were the least Synchronized top groups? Don't know what exo good dancers or choreography have to do with them being out of sync

Groups of four members will always appear less synchronized/messy compared to more numbers. Formation is science. Every four membered group got dragged for that. BP, Mamamoo,aespa, 2ne1. Even groups who I find were good got that drag like MissA. People dragged Suzy’s dancing.

Aespa in BlackMamba were phenomenal but the choreographies got weird after that.
