There are three major reasons why one might prefer a gold nib to a steel nib.

• Flexibility: It is widely considered that gold nibs give greater writing character and a wider degree of line variety. A gold nib will also adjust to one’s handwriting style as it will soften over time. This reason is considered secondary for most fountain pen users who choose gold nibs.
•  
• Prestige and presentation: A fountain pen with a gold nib will have been created with much thought devoted to the design as well as uncompromised craftsmanship. The result is a pen with unparalleled aesthetics which ensures that a gold fountain pen is more than just a writing utensil but truly a statement piece.

• Anti Ocidation in contact with humidity etc.
