For me the primary benefit in going electric is if all of my summer yard tools can be electric and eliminate the need for gas and maintaining gas engines alltogether. This particularly for infrequently used gas engines. This is a benefit to the Echo PAS system - the same engine gets used frequently even though individual implements do not. I only use an edger once or at most twice per year so it doesn't get used enough to keep running well. If I can't replace everything or nearly everything with electric then I'll still have a problem of infrequently used gas engines. Hope this makes sense.
