People always say Niskanen has the best classic technique but I don't think it's that black and white. It depends on the terrain and the form of the skiers. For example, in that first section in the video in Lahti, I think Bolshunov has a slightly better technique, although it is close between all of them. Also, in general I think people underrate Klaebo's technique. It's not perhaps as powerful as the other two, but it's incredibly elegant and viewed from the front, maybe the most beautiful.
