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

I’ve been doing some research and I’m wondering which one would be better for me. I have an under developed chin and do not want jaw surgery because I’ve already had braces 10 years ago. I do have problems with snoring and my mouth stays open with sleeping so I’m leaning more towards a genioplasty. I also have a deep mental crease and from what I’ve seen an implant won’t help. Obviously I need to make a consultation but a pre-opinion is always helpful.
