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.
JLS were the runners up on the 2008 version of UK show 'The X Factor', losing out in the final two to Alexandra Burke.
