Snapback vs Full Cap

Snapback M&N Chicago Bulls

Full Cap New Era Atlanta

Some people say that Full Caps looks better. For me Snapbacks are more practical. It has seven possible sizes so it fit on every head. Few months ago snapbacks became very popular. American superstars started to promote them. They wore it everywhere. On the street, during the concerts, on the beach. 

Full Caps became famous at the end of the XX century. Baseball players started to wear them during the games. Now every baseball fan have the Yankees or Red Sox's cap.

So, which do you prefer, Snapback vs Full Cap?
