Their music is bop and they both are so talented, Also they have a lot in common plus they have totally different makneas which is kind of nice I guess, And now Jungkook is a hyung, Not the youngest idol because txt's debut came up and now they are the youngest idols in Bighhit.
I support both, And I definitely don't believe that its only cuz of bighit, They came to be under bighit the same company as of BTS, That they are famous.
I mean, Cat and dog is a bop.
The reason why I would prefer BTS over TXT is because I know them more and feel a stronger bond. I would prefer BTS over any other kpop group because I love them so.
