NO - There is no good reason electrically... Only what works best for your particular system layout.
In my particular case I am using four batteries which have their NEGATIVE GROUND terminals all going to a separate FRAME GROUND connection. All of BLUE SEA sealed make before break high current switches are installed in the POSITIVE side of the batteries. In this layout the only single point place to totally DISCONNECT the 12VDC from the system would be in the POSITIVE side of things.
Consider my battery bank layout currently being used on my OFF-ROAD POPUP trailer.

My totally BATTERY DISCONNECT is the OFF POSITION of the first four position Blue Sea switch labeled BANK1 - BANK2.
