I haven't seen enough of Platini to make that judgment.
Anyway I find it funny when comparing these types of legendary players and saying who is better just like that x>y. Both of them were greats, different times, both of them had different qualities that were better then the other ones and both of them had major impact for their club and national teams.
IMO they both were one of the greatest players of all time and that is enough for me. Definitely not gonna handpick specific moments of their career to get into the argument who was better or worse.
