Summer Fan Showdown is a month-long competition on PopCrush to determine this summer's most dedicated fan base.

They might not be together at the moment, but there's no denying that the boys of One Direction — as a troupe or solo — are still killing it in 2017. From Harry Styles' acclaimed debut solo album to recent efforts from the likes of Liam, Niall, Zayn and Louis, One Direction is still all over the charts like always — and their faithful Directioners will follow them any which way they go. But will they push the band through to the second round?

If Twenty One Pilots proved anything after their Chart Achievement Award at the 2017 Billboard Music Awards, it's that their fans should not be underestimated. The "Heathens" duo is due for a hometown tour this month, the Tour De Columbus. Will their Clique be riding with them just as hard this summer and pushing them into Round 2 of the Showdown against 1D? We'll soon find out.

This poll is now closed. Head over to Round 2!
