Yes, and WSJF gives you two units of data: priority and sequencing - because everybody's pet is priority 1. Much better than MoSCoW.
Particularly when you get the decision makers in a room and get them all to agree on the estimated value of each item. Not only does it remove the numerous priority #1's, it also gets everybody aligned on what the real priority #1 is and why.
I've seen it done where people are surveyed separately and it only works well when the people involved are forced to have a conversation to put real numbers to their assumptions, coming out with agreement. The other side effect is that it solves the squeaky wheel problem.
