A little late to the party, but I switched to a corded electric mower and I have no regrets at all.
The big selling point is the low weight. It is hard to imagine how much lighter it is compared to a gas or battery mower and I frequently mow my yard with just one hand.
I had a battery mower for a few years and replaced the lead-acid batteries twice. I know the newer Li batteries are lighter, but they still weigh more than no batteries, can't match the power of 120V AC, and will degrade eventually.
There are certainly conditions where a gas mower is preferred, but I find them noisier, dirtier, smellier, and require more maintenance than electric, at least for my suburban lawns.
