ford versus jeep hubs.

I searched a few can't seem to find the info I am looking for. I thought I had seen a thread a few days ago about the difference between these hubs. Does anyone have any idea's as to which is stronger? I Have the manual hubs from the f.s bronco(79) and the are different than the jeep style that came from the f.s jeep. Not a very good picture, the ford style is on the left and the waggy on the right. Anyone?

Dave Taylor here was going to try the spicer style (left). I'm not sure what his conclusion was.

The style on the right are the standard Warns. I would venture to say the spicer style is stronger.
