The circumstances surrounding them are totally different. The Voodoo tour was after an album release so everyone in the crowd already knew all the music. With this tour the crowd is hearing a good chunk of the set for the first time. That in and of itself will completely change the energy of the show.

Also, throughout the Voodoo tour some of the arrangements evolved - you can hear this when you listen to the same song in different venues. By the end of that tour the arrangements were pretty complex in what the band was doing. On this tour, it's just a month long so the band isn't gonna have the time to develop their chemistry to that level. Plus because there are new songs that the crowd hasn't heard yet, you don't want the arrangements to be too complicated, or people won't get to know the music for what it is.

One thing I've noticed is that D seems to be showcasing his voice more in this tour, which makes sense. The main goal of this tour is probably to let people know that he's still got it, and him showing how strong his voice still is is probably the best way to do that.
