Silicone implant vs. rib cartilage for Korean rhinoplasty - which is better?

I am considering rhinoplasty in Korea and cannot decide between silicone implant and rib cartilage (autologous) for my nose bridge. I understand that silicone is more affordable and has shorter surgery time, but I am worried about long-term complications like contracture or implant visibility. On the other hand, rib cartilage seems more natural but involves harvesting cartilage from my rib, which sounds quite invasive. For those who have had Korean rhinoplasty, which method did you choose and why? How has your nose held up over time? Are there any other materials I should consider?
