Intuitively,6 dof tracking is much more immersive because it gives human brain a sense of "control": the state around you changes once your head moves around. This applies to controller as well i.e. when your hand moves, the controller in the virtual world moves around as well. Many VR brands went a step further and enables finger-tracking for their controller, or even through raw cameras to achieve a more sense of control around the users fingers, for example: Valve Index's finger tracking controller & Oculus Quest's ML powered finger tracking algorithm
