Probably faster. With a BNC connector, unless you have a real fancy
stripper, you first have to strip off material leaving the core conductor,
then strip off some more to expose the ground shielding. Then you have to
hope you got the lengths right. Then you must spread out the ground
sheilding to accept the connector. Put the little pin on top of the
center conductor, then you have to make sure you've put the metal crimping
ring on the cable BEFORE you've spread out the ground shielding and put
the connector on (argh! how many times have you done that?). Squash it
all together, move the ring up and over the shielding, then crimp, hoping
none of the shielding strands are sticking out making it look ugly.
RJ-45 is strip the shielding off, arrange the wires in correct order,
insert them into the connector and crimp. It takes a little times as
well, but not nearly as much time as a BNC connector takes, and it's far
easier and much less prone to error than the BNC. The worst thing is
crimping a damn BNC connector for the third time and it STILL doesn't
work. With an RJ-45 you can at least see if the wires have been inserted
all the way by looking at the end of the connector. And you can do this
before you crimp it.

I tend to prefer structure over chaos, at least where my technology is
concerned.

Reason enough for me!
