It seems that it is really a matter or the nature and regularity of use.
If you use one a lot, the convenience of gas, and the power from a gas device is likely much superior. If you use it seldomly, while Im not one to ascribe to the ethanol boogey man, the electric unit is likely better for boxing up, putting on a shelf for a while until you need it again.
I cut down small trees with an electric saw with my Grandfather when I was young. He rarely used it, so it was all he needed. My parents and I each have a gas saw for home use and for use at the mountain house, and while they dont get "regular" use, the flexibility and duration we use them for justifies it.
It truly is a case by case basis. I prefer gas OPE, but wouldnt turn down an electric unit if it made sense practically.
