artRAVE without a doubt for me. The Prismatic Tour is just a screen with some lights and props and gimmicks, whereas the artRAVE's staging alone is better than most of the Prismatic Tour. The artRAVE focuses less on gimmicks and more on just Gaga, her dancers, and the production. She doesn't need to float across the crowd or reduce herself to a child playing on a cat house.
But, everyone's entitled to their opinion so people who disagree with me aren't wrong.
