It really is just a personal preference.
One method is not "better" than the other.
I like the convenience of electric starters and electric fuel pumps.
Charging the field box battery is no more inconvenient (to me) than charging the transmitter and receiver.
I have all of my wall wart chargers plugged into a long power strip. I flip the switch at the end of the strip on Friday when I get home and flip it off Saturday morning when I'm ready to load the truck.
