for me, Bodukan had a better audio mix and they captured the audience response better than UU06.
in united the audience was severly muted, and the mix was very muddy. the best way to tell is to listen to the drums. in budokan it was crisp and clear, in UU06 it sounded dude was tapping on a wet paper bag.
UU06 blows budokan away in stage presentation though, those massive L.E.D. curtains, those were the shit. the lighting way perfectly synced to the moods of the songs and of course the updated arrangement on some songs were refreshing to hear.
