JLS are very successful. They have had various number 1 hits and have won many awards.

Katy Perry is a worldwide artist and has been in the music industry longer than JLS, so at the moment, she is more successful. But in the UK, JLS have had more number 1s, so JLS are more successful than Katy Perry in the UK only.

It depends on the person you ask. Personally i think that there is no competition because JLS are definitely better. But I'm a mega JLS fan! lol But if you ask a wanted fan then they would disagree with me and say the wanted are better. I know that JLS are way better because although they haven't been in the music business for too long they have been massively successful and will carry on being a-maz-ing!
