Are fat transfers to to face better than fillers long term?

Hello I am 27 years old and have not had anything done to my face. But I already know that I am going to have to get some things done soon due to volume loss. I am thinking long term. Are continued fat transfers to face over the years or continued fillers to the face a better option? My problem areas are under the eyes and smile lines and as I get older to the tops of my eyelids. I'm wondering which the body handles better over time and which has the least potential to cause complications. Any advice would be appreciated
