The best last name a Mexican can have, since it isn't like the common Mexican last names. Example; Lopez, Hernandez, Fernandez, Ruiz, Juarez, Ortiz, Mendez, Alvarez etc. Notice how a good majority of them end with a 'z'. The only downside of having this last name is people butcher it so badly, especially gringos. Other then that, having this last name means you are a cool ass Mexican.
