What hurts more the Belt or Hairbrush ?

Someonne told me the hair brush hurts more which I think is wrong because with the belt they have more swing power but I could be wrong. Please answer if you have been spanked by both of these omplements and which one hurt more and why you think that. Yes I know each person has a different experience and each bum it different. Please also write how the two implements were used on you. Meaning position and whether pants up or down or underwear up or down, Thanks
