Hi Dan and the group,
Well, it is certainly easier to solder if you can position the gun and the solder while they are cold.
But, like most things, there is a drawback.  It usually takes around 30 seconds for the gun to heat up.  During this time, the components are exposed to the heat.  If you use a soldering pencil, it is already hot and melts the solder almost instantly.
But, I still use a gun for most connectors and wires.  It is easier to grab a soldering gun, instead of waiting for the pencil to heat up.
I hope that this helps.
73s,
