The obvious advantage of a quick disconnect is that we can quickly swap out parts. Our team usually only uses this connection for disconnectable subsystems, or motors that like to burn out.(cough, cough banebots...). Although not really related, you can use quick disconnects so that pairs of wires can only be connected in one way, and you can easily find color-coded disconnects as well.

Terminals are mountable (depending on the terminal), and make solid, low resistance connections. We use these for things like power to sensors, camera, and other things whose wiring is not likely to be changed/removed. A little super glue (or nail polish for a strong but temporary hold) can ensure an "out of sight, out of mind" connection that can be hidden inside a robot.
