I have used the electric, but the dependence on a battery is planned failure. All the batteries come from China....look before you leap. Gas chain saws have been around forever with a very long shelf life. The Pre mixed gas is good for two years in the saw, 5 years in the can and this ends all issues with gas chain saw starting up.
If you go electric, I urge you to consider a 40V a minimum, but a quality saw and the extra dollars will pay off in many less problems, Oiler quality, blade adjustment ease. As the battery gets weak on the electrics I have used, this causes an undue strain on the saw, keep a sharp blade and an extra battery handy.
Best wishes!.
