Question about the difference between Denserty Lifting and Thermage

My facial elasticity has noticeably decreased, so I am looking into lifting procedures.
Many people around me have recommended Thermage, but recently there have also been many reviews for Dencerty Lifting, so I am having a hard time deciding which of the two procedures to choose. I have heard that both use radio frequency (RF) principles to deliver heat to the dermis layer of the skin to induce collagen regeneration, but I am curious if there are any differences in the actual effects felt or the duration of the results.

I trust Thermage because it is a device that has been proven over such a long period, but the price is quite burdensome, and I found it difficult to make a decision readily due to reports of severe pain. On the other hand, Dencerty uses two types of radiofrequency energy together, so it is said to be less painful and cost-effective; however, I have doubts about whether I can actually expect the same tightening effect or longevity as Thermage.
