Now that we've had ample time for the PRISM singles to marinate in our heads, and seeing as there will be no more singles from the era (as confirmed by BB and her label), which single was the best?

Roar
Unconditionally
Dark Horse
Birthday
This Is How We Do

dark horse, DUH!

It's between Unconditionally and Dark Horse but i'll go with Unconditionally.

Dark Horse, no second thought.

Poll added

"Dark Horse". I keep forgetting about Uncle's existence.

Dark Horse is Katy's best song, so this.

Dark Horse easily.

The only one above a 5/10; Birthday.

Walking on Air

Uncle or TIHWD, I can't choose

Dark Horse > Birthday > the rest

Roar > Uncle > Birthday > This Is How We Do > Dark Horse.

Roar > Dark Horse >> Unconditionally >>>>> Birthday >>>>>>>>>>>>>>>>>>>>>>>> tihwd
