At least her star-power, touring capacity and industry presence multiplied during the PRISM era.
And I honestly think that the PRISM era videos are better overall than OOTB.
Ur So Gay vs.
Roar
I Kissed A Girl vs.
Unconditionally
Hot N Cold vs. Dark Horse (but I wish HNC didn't look so MQ and dated)
Thinking of You vs. Birthday
Waking Up In Vegas vs.
This Is How We Do (almost a tie)
Obviously the TD era is her best visually but even that has some duds (TD, 2/3 of ET, the cheesiness of Firework and POM)
