I have to say Bulls. Not just because of Michael, but because of the same reason the Celtics of today, for example, beat the Cavs: TEAM effort. The 96 Bulls were the best Chiacago team ever, each member was at their peak with the individual talents, hence 72-10. And by 86, Larry's back was already killing him, and Parish was in decline. Also, I believe Ainge's best shooting years were yet to come.
