I 愛 all of them<3 But I'd say Big Bang, because their debut was 8 years 前 and they are one of the best since then then B.A.P and EXO They're too young groups to say better than Kings Big Bang
EXO!!!!!!!!!!! Why? __Simple,its because I like them and out of all K-POP groups...they have the members who are true & very Charismatic!!!!!!!!!!!!hahah 愛 EXO <3 EXO-L fighting!!!!!!!!!!
Ahmm... I think it's BIGBANG. Because I like there musics A LOT! And I'm a big ファン of them. They are just different from the other groups. I like how G-Dragon Composed there own songs! So, Yeah! Bigbang is the BEST!
