The 8 pin modular connector as found in most ethernet does have several sins but it has one huge redeeming feature, A feature I wish was found in every cable. It is easy to field terminate. Have fun putting a new end on nearly any other cable.
Every single time someone has provided pre-terminated cabling for one of my jobs to "save time" or to "make it easier", this provision has done neither.
Instead, it has consistently multiplied both the time required and the installation difficulty. It has done these things while also producing an inferior end result.
It is my anecdotal observation that it's NFG.
