This poll is not considering the eras, only the tours that each era had.
Both of them are epic, but very different. Back when "The Femme Fatale Tour" started I thought the tour was billion of times better than "The Circus Tour Starring Britney Spears", but I guess right now that has changed.
I saw "The Femme Fatale Tour" as a real Britney Spears being there, since it was not that complex so she hadn't all the production covering her image and stuff. Besides she included way more "Femme Fatale" songs on it and her entrance was epic. She seemed more into choreography and thiner. And the best thing: she looked happier! By the way eventhough not a lot, the interaction was way bigger and there was no bloopers!
But these last days I've been all over YouTube watching "The Circus Tour" and I fall in love with each performance I see, even if I didn't like them as much! And I feel more energy!
Obviously comparing the money made in eachother "The Circus" SLAYS "The Femme Fatale" but we have to see that "The Circus" was the COMEBACK, so it's completely normal.
A thing I appreciate in "The Femme Fatale Tour" was that the storyline was actually really cool and "The Circus" didn't have that much of it.
Anyway comparing the performances of the songs that were used in both tours we can give it a little comparisation:
Piece Of Me: In my opinion, Circus Tour destroys Femme Fatale performance.
Womanizer: Here they kinda are equally great BUT, in the Circus Tour that oufit was EVERYTHING!
Slave 4 U: I'm an original choreography stan so gotta go with FFT;
BOMT: Circus Tour slays as well.
Based on this I would have to say Circus Tour but still I love Femme Fatale Tour. This is tough, and I would like to know what's your opinion so I could compare with mine! Give a decent critic!
Let me add that the outfits of The Circus Tour slays most of The Femme Fatale's!
