That is the same as asking D44 (eliminator) vs. D60 (30-spline longfield), which is a no-brainer question in terms of strength
30-spline longfields transform a 8" Toyota axle into the strength of a D60.
If you ask me, I would NEVER run universal joints over cv joints unless there was a huge significant gain. Using D44 axles is definitely not what I would ever want. Especially when a Toy Birfeld is stronger and maintenance free.
