My childhood was more interesting because as a child,one has nothing to worry about. Your parent provide you with everything(food, cloth,shoes and so on)
Children don't worry about things adults worry about like the economy, next payday,bills, debts and so on
During festive season,children get gifts from parents,neighbours,and so on but as an adult,you worry about how to provide this things for your children, parents, siblings and so on
Childhood is more interesting because you don't worry about where your next meal is coming from. If you fall sick,your parents take care if you but as an adult, you can't afford to be sick because you will foot the bill yourself.
With all this,I prefer to say that childhood is more interesting
