Same. One difference might be how much stress we put on the machine. I believe thermal paste does degrade faster with more heat and Christian says that he throws a lot at it: video editing, code compiling, CAD models. It might make a difference how much usage is being put on the machine leading to degradation of the original thermal paste faster or slower.
