Who gives out better/more Halloween candy; the rich neighborhood, or the middle-class neighborhood?

I live two blocks away from a much wealthier neighborhood than my own (literally across some railroad tracks). The neighbor kids think they will get more and better candy in the richer neighborhood. I think they’ll do better in ours.

I suppose I’d need identical twins wearing the same costume to do a proper test (eliminate the costume/cuteness factor). Since I can’t do that, I’m gonna ask here. Where does one get the most/best candy on Halloween? Rich or poor?
