The basic difference is install. Presuming that the Omori are similar to the other brands, for the mechanical gauge you just place a tee in the 1/4 line that runs off of the BOV for the pressure. This line then runs back inside the cabin to the gauge.

The electrical gauge has a MAP sensor that has to be installed, in line with that mechanical tee.

If that MAP sensor breaks/fails, it's expensive to replace. That mechanical tee in the turbo line is under a buck.

The electrical should be more accurate, but is it worth the price difference to you? It's not like you will be reading the gauge all the time while driving.

Depends how you look at it. Are they purely diaphram driven mechanical boost gauges? I'd bet that the mechanical parts of the gauge wouldn't be as reliable over the test of time as the MAP sensor.
