As far as stronger axle or comparable, the Dana 70 is about equal, a Dana 80 would be the next step as far as axles in factory form.
I agree up until you say the dana 70 is about equel, it is in its ring but its the pinion that will give out before anything. The dana 80 we can't even put into the same slot as the 14 bolt or Eaton as it has a 11.25 ring and a massave 37 spline pinion.
No one here along with me is going to say a 70 is weak, they are not, but IMO the list of axles go 60, 70, 14 bolt, HO72, then onto the 80.
Your right about the 14 bolt being the most popular as they are every ware, easy to work on and realy have no factory weak links, except for the tubes spinning which is an easy fix with any good welder.
I say it all the time in the HO pirate thread, if the Eaton axle still had a strong after market support then the super 14's drop out sectoin would have modled after the Eaton since its all ready a drop out 3rd.
