Which axel is stronger the dana 44 or ford 9?

a dana 44 is on the front end of most of the older and some newer dodges, fords and chevrolet, a dana 60 is a strong rear end, as is the ford 9 inch, after that there are all kinds of really expensive hard to break rear ends. all my mp[ars had a dana 60 and I tortured mine so I know thats one tough mother. it never broke and I fried a lot of tires with it. hopefully someone else can come up with the other stuff.
