Stage: I like the MDNA one more because of how its used. The artRAVE one is really cool especially the lights, but its so high that you'll always be craning your neck. The awkward shape of it makes it so weird of how she's running around to use it and the pop up trees/mushrooms during Venus look like they block views.
Setlist: artRAVE has a really good continuous upbeat flow of songs, but so pressed af that Fashion! and the Cake Like Lady Gaga interlude got cut out. I wish the MDNA Tour added a song or two from her older catalogue, I'm so glad I got to hear Holiday 2/3 shows I went to.
Outfits: Madonna's Transgression and Masculine/Feminine outfits alone just completely slay effortlessly. The only artRAVE ones I like are the opening (without the wings), and the encore outfit, especially with the long wig. The new black latex bikini one is growing on me (and I seem to be a minority).
I have to give Madonna the edge on this one though!!!
I really liked the artRave. The set and the performances were great, the light shows being the best part. I haven't been to the MDNA tour, but if i wanted to choose between the two based on photos I'd choose the artRave. But i'd also choose the artRave because I'm not even sure Madonna has an intriguing voice while performing live.
