Unless I'm wrong, I believe you'll be holding Knuckle controllers just as you hold Touch, regardless of whether you're gripping something in VR or not. The only difference will be when you open your grip just before grabbing something, instead of just pressing the grip button on Touch when grabbing something.
The reason I say this is that you need to be firmly gripping the controller to operate the other controls (movement etc) and to provide firm stability to the controller whether gripping something or not. If this is the case, then you're really just making quite a subtle difference to the experience.
But what might make a larger difference (at least for me) is having the constant touch of the strap across the back of my hand. This may, for me, contribute to having a reminder that you're using a controller rather than add to immersion.
Don't get me wrong, the old Vive controllers are overdue for an improved alternative and Knuckles are definitely that, but I'm not sure the grip mechanic is adding to the experience or detracting. Am I missing something?
I welcome alternative thoughts.
