I bought a Toro e-Cycler about 10 years ago - it's been good.

My lot is small though - 50' x 110', with much of that taken up by house, garage, and driveway. I don't need to stop to recharge between boulevard, front yard, and back yard. When the time comes, I don't imagine that the three 12 V batteries will be costly to replace.
I liked the steel body of the Toro, vs. the plastic body the competitors were offering at the time.
My old gasser had gotten very finicky, and Home Depot had a "push, pull, drag, or tow" your old gas mower in for $100 credit toward a new electric. It's often difficult to find a spring or summer day here when the grass is as dry as I'd like. When the grass is a bit wet, it clumps up underneath the chassis, above the blade. So, I want to tip the mower over and clean out the wet grass. But, with the gas mower, this meant spilling gas and oil, and usually a flooded carb. I considered building some sort of ramp thing I could push the mower up on, and then clean the grass from underneath. If you leave the wet grass in place, it starts to rot pretty quickly, and stink up the garage. In contrast, cleaning out the electric mower is really easy, and yes, I always remove the interlock key before turning the mower on its side to clean it out.
No more stale gas or stabilizer to worry about either.
Ultimately I think it comes down to your lot size and tolerance for having to recharge partway through.
