I think Michael's Energy on the Victory tour was amazing or at least it looked that way with the performances shown, he was hungry to get out there especially after the success of Thriller, I still think it would have been more Successful if he had done it solo.
The Bad tour was great Vocally, he was more comfortable and in charge, he was the captain of the ship for the first time in years, so he could sing and say anything, the show was all his, great moves also especially in performances like Human Nature and Shake Your Body, again the energy on Heartbreak hotel, shake your body was there, this was the last tour MJ sang all live.
The Dangerous tour....EPIC!! but from a technology perspective, everything was bigger, sound and stage effects were like nothing heard or seen before, as for the show itself it has its moments especially the intro (Jam) and Outro (Man in the Mirror)
The HIStory tour... lets just say if he didnt kill the Stranger in Moscow performances i would have considered it an utter failure
