Do you think it would be better to be an only child or have brothers and sisters?

With brothers and sisters, you always have somebody to play with.  Without, your toys never get broken.  With you learn to share.  Without you don't have to.  With you have somebody to stand up for you at school.  Without you learn caution.

You get the picture.  There are plusses and minuses. 

When you are grown, these are exaggerated.  If something happens to your parents, siblings will join together to help and singletons must deal with it by themselves.

I had siblings and envied the singletons I knew because they didn't have to share anything especially their parents.  Now, that we are older, they have no family other than spouses and children.  No nieces or nephews.

I think I am happy to have had siblings.
