Is Personal Statement or Supplemental Essays more important?

Obviously, they’re both important, and obviously I’m gonna put my best effort in all of them and make sure they’re both good.
But, what would you say has more importance — say, a 650 Personal statement or a 400 word supp?
What if a school has two supps? Are those two supps collectively about 2 times as important as the personal statement for that school specifically?

I don’t think there’s any way to say. In fact, I’d say whichever essay makes the admissions officer say, “Wow, this kid would be fun/interesting to have in a class/as a roommate.” I suspect that for my younger son, at Tufts it was a supplement essay, at U of Chicago, he got a comment from the AO about his funny “Why Chicago essay”. Most essays don’t make much of a difference at all. One AO said at a school presentation, "A few essays are so wonderful that they might make a difference. A few are so terrible, that they negate anything good in the application, but most just confirm what they’ve already heard from teacher recommendations, and the other material in the application.
