Maybe not a stupid question.
There appear to be more Woodall candidates than Cullen. For example between 17M and 18M, there are 27'992 Woodall candidates, but only 20'304 Cullen.
So there is more work in advancing Woodall.
This corresponds to the fact that there are more Woodalls known than Cullens. (More candidates after relevant sieving means more primes found.)
So the "weight" of Woodall is higher.
