Overall IMO the dana may have a tiny bit more strength since it has more splines unless you get one of the 30 spline 10B's. Other factor is if the axle shafts in the D44 have the smaller u-jt's... that's not good. Not worth dealing with unless you are changing gears... if you want strength get aftermarket axles of a FF kit for it ... or a Dana 60
Both are pretty much equal in many areas. One has some weaknesses and the other the same. I will look for an article in a magazine that you can refer to.
