Why? What benefit does a gas powered weedeater have over a battery powered weedeater when trimming around a acre lot?

Having to get a gas can filled at the gas station? and buying the little oil to add to the gas?
Gas engine breaking down/wearing out?
Water getting in the gas/old gas?
Buying air filters every year?

Which benefit do you like the most?
