Best version of what?
It seems you are talking about best version between official live DVD's only
I've never really liked when fans (not only U2 ones but from all other bands) express for a particular official live DVD "BEST CONCERT EVER !!", "GREATEST PERFORMANCE EVER MADE", "THE BEST CONCERT OF ALL TIMES", etc, etc without having watched any concert other than the official ones
That's pretty easy and comfortable to say, and it belongs to casual fans, not the ones who watch and listen to bootlegs.
Any performance of Where The Streets Have No Name with Bono talking, screaming and making noise just because at the begining of the song (Elevation - Vertigo) simply can't be the best
The best visual effect is when the stage goes all in a deep red (Under A Blood Red Sky ...), with just the beautiful sound of the keyboards and some Larry cymbals, and suddenly Edge comes with his sublime guitar riff
. Then the full band play tight and elegant and then the flash lights blind the audience. That's the perfect moment, experience heaven for a couple of minutes. Bono's speech, screams, or whatever he comes to mind at that moment are always completely useless, silly and disposable. He just ruins that uplifting moment !.
So the best versions of Where The Streets Have No Name you'll find during 1987 - 1993
The Popmart versions aren't as good as the previous ones because of the annoying sound sequence before Edge Guitar. That's just criminal! they killed the keyboards by replacing them with an unforgivable synth!
