I'm assuming it's just more flexibility with bulb choice and less power consumption?

as far as I am concerned non. the only thing electronics do is run cooler and use less energy, but this is at a cost. On average an electronic ballast will only deliver 360 watts to a 400 watt bulb so basicly it underdrives the bulb. this applies for the 250 watt ballast also.

If you are going 250 watt and you buy a M80 (HQI) ballast you will be able to run any 250 watt bulb out there.
