Right Tool for the Job. 

I use barrel connectors when I _want_ the cord to come out when the unit falls off the shelf rather than dangle by the power cable. 

Locking Molex, or, far better, locking AMP connections when I want the unit to hang by the cord when necessary. 

We've gone to 9 pin circular locking AMP connectors for rotors on our 2x /year ham radio contest set up on the mountain (take a look for W2SZ / MGEF). Waterproof (not water tight), sturdy, impossible to misalign. And 40' of cable can hang from one for a few minutes if need be.
