Who had tougher competition, Michael Jordan or Kobe Bryant?

Me and my brother were talking about this the other day when the NBA playoffs were competetive and rough. Jordan vs the BadBoys of Detroit! Man they would bang him up then.. Joe Dumars, Rodman, Thomas, and Lambeer.. that was a rough 7 games! The Knicks who had Starks, Mason, Oakley, Ewing! That was a riviarly that led to fist fights and sh!t. Their no doubt that Jordan had it rough boy. Kobe doen't have rivialry? Let's see.... The only one i can think of is when the Kings took them to 7 games when the kings had Webber, Bibby, Christie, Pejsa, and Adlemen as coach thats about it.
