34, genetic jaw and neckline. Short Scar Neck Lift or Platysmaplasty? (Photos)

I’m 34 years old and I’ve never had a defined jaw or neckline. I’m in good shape and not overweight so this is purely genetic. I’ve met with two surgeons, one of whom reccomended a short scar neck lift and the other platysmaplasty with neck and chin lipo. I’d like an option on the differences / which would be better in this case. And whether just lipo alone might give me a good result (neither surgeon seemed to think it would). Thanks in advance!
