I think I may understand the question so I will give it a shot
I do deficit deads after regular deads usually in the 3-5 rep range for 2-3 sets. Deficit deads train the bottom end of the deadlift and the movement itself. I would call it a an assistance movement rather than a quad or hamstring movement. Your question is kinda vague to give a good answer to. If your goal is to get a better deadlift, then think of Do the deadlift as the main lift, then Deficit Deads as the assistance to the main lift, then your individual quad and hamstring movements.
Main movement Deadlift (works damn near entire body)
Assistance Deficit Deads (works damn near entire body, not a specific quad or hamstring movement)
Then hamstring movement (GHR, RDL, Leg Curl, etc…)
Then Quad movement
and if you want extra ham work add another hamstring exercise.
The first two train the movement, the rest train the muscles involved. Or if your question is asking totally something else than I have wasted everyones time.
Fuck now I confused my self…
