Out of these choices, I would go with Munich or Wembley, because you can hear MJ singing over the backing track. Munich especially is a nice performance, imo.
Not included in this poll, but also favourites of mine are the This Is It performance and the MTV performance. For the TII performance, the live vocals were very nice and the band sounded great - I always felt Black or White did not sound as great as it could on the tours. The MTV performance features great dancing.
I always hoped Michael would incorporate a bit more of the choreography of the short film in his live performances. I loved the different moves he did in the short film, and felt they really fit the worldly theme of the song as well. He never really did during the tours, unfortunately, but does bust some moves during the Dangerous Tour rehearsals. Therefore, I really like that performance too.
