Septal cartilage, ear cartilage and costal cartilage (rib) have very different characteristics and should be used for different purposes.
The ideal cartilage for rhinoplasty and revision rhinoplasty is septal cartilage but the availability of it may not allow its use if the previous surgeon has already removed and used it or if the cartilage is small and inadequate.
Ear cartilage is easy to harvest but it is thick and floppy and not ideal for most uses but most plastic surgeons feel very comfortable harvesting and using it. It is not ideal unless a composite graft is needed which has skin attached to the cartilage and used in the nostril area.
Rib cartilage is nice because it is strong and abundant but harvesting it takes more skill and carving it properly takes even more skill
