Marty Moore is a strange one... I don't mean the rumours, I mean his performances.
In some games, he appears to be a stronger scrummager than JCW, but in others, it's the other way around.
There's obviously a number of factors, including injuries and fatigue, but also that sometimes your technique matches up better with certain opponents.
I'm still not sure who the better scrumagger is, but I'm usually happier when JCW is starting.
I wonder if any new potential TH would be as a starter, or as 2nd choice / compete with JCW
