As a one off test, it isnt very conclusive.

Multiple joints would need to be broken to truly prove any one better then the other.

At the end of the day, all it proves is that you get a similar joint for less money.

CTMS are more proven to last in fulltime hub vehicles like jeeps.

Longs are not as tested, but may last just as well. Its the risk you take.

Jack (ctm) is better known to be easier to deal with.

In the end, pick your poison.
