Pre-fader metering for the normal audio-faders is standard. I dont know wether this setting applies for the normal faders, or only the aux/master faders. You can use this setting to see what the actual level is. This will be the same as when you set your fader to unity. Prefade metering will also give you a tool to see if signal is present or not.....

In my opinion it doesnt matter what you use, just use what you like best....
