Deep plane vs SMAS
Two facelift philosophies, one honest comparison.

Both techniques work beneath the skin, on the layer of fibrous tissue that holds the face together, called the SMAS. They differ in how far the surgeon goes beneath it.
A SMAS facelift tightens and folds that layer from above. A deep-plane facelift releases it from its attachments and repositions it as one unit, which moves the midface as well as the jaw.
Deep-plane results tend to last longer and look less pulled, but the operation is longer and requires specific training. For a heavier neck or an earlier stage of ageing, a SMAS lift may be the better fit. The drawing decides.
The question is not which is better, but which your face needs.
