Let's talk about DeclanGalbraith and JustinBieber, who is more popular now?

I think it's Declan Gelebrais. Although Justin Bieber is a newcomer, I think Declan's debut time is a little longer and he is still popular, which proves that he is very talented. Moreover, he made his debut when he was very young, and now he is still popular, which proves his strength. I think Declan Gelebrais should be more popular.

But everyone has their own differences, and everyone has their own reasons for who they like, so the above is just a personal opinion. I hope you don't mind.
