Should I get a chin implant or sliding genioplasty? (Photo)

With your young age and degree of chin deficiency, a sliding genioplasty would be a better choice over an implant. The depth of your labiomental fold is always problematic but there are better strategies with a sliding genbiopplasty for some improvement in it than with an implant.

A chin implant can be placed under local anesthesia as an outpatient procedure which takes 30 minutes, and is much less invasive. A sliding genioplasty is performed under general anesthesia in a hospital setting with an overnight stay and is much more invasive. A sliding genioplasty is usually performed when the teeth are significantly out of alignment.

In your case, a genioplasty is the choice. However, the surgeon has to consider the depth of the 'fold' between the lip and chin; and ensure it is well supported or it will not look natural and balanced. The genioplasty also 'pulls' the tongue forward to some degree; so it may assist the snoring/breathing. An implant does not improve tongue position.
