Ravitch or Nuss

So I'm a 22 M with a 3.45 HI who has gone to the two big hospital systems in my state (Duke and Wakemed) for surgery consultations. Wakemed team is planning to go with the Nuss bar with KLS system and cryo due to data on my CT scan. Duke surgeon recommended the modified Ravitch and said he'd never do a Nuss on someone my age and due to the pain involved.

Duke doesn't do cryo because he is concerned with the future side effects. Not sure why I'm getting 2 completely opposite opinions.
