The other mower you mentioned is 24V x 5Ah x 2 = 240 Wh.
Practically, I have found higher AH rated batteries giving better performance even in the same tool.
Considering all this, I would always go for the higher Voltage tool and higher Ah rated batteries. I am not an expert at all, and welcome other people to chime in with their experiences and thoughts.

I have had 3 older corded mowers, 18" and 19" Black & Decker, and a 20" Homelite, all rated 10 Amps. They are all underpowered compared to a gas mower. Tall thick grass requires slowing down, sometimes a lot. I'd guess it takes me 50% longer to cut lawns than a gas mower of similar blade length. I don't know if you can buy more powerful corded mowers now or not. I'm satisfied with the tradeoffs, since it's cheaper than buying a good cordless and batteries. Cheap used corded electric mower are easy to find on Offerup (my last cost $35).
Until this year I'd only had gas mowers my entire life. As a kid we had a lousy push Craftsman mower. We had a Honda snow thrower that was amazing so I convinced my father to buy a Honda mower (despite him working for a "competitor" to one of the Honda divisions) and that thing was ah-maize-ing. Ran forever despite us abusing it like crazy and yeah, suffice to say, I am a HUGE Honda small engine fan.
So when I bought a home a few years ago, it was a given I'd buy a Honda. Only, we "inherited" a lousy gas mower and I have this aversion to spending money I don't have to. So I lived with it. I hated it, but the thing refused to die.
Someone told me about a local (city/county) program that offers a $300 rebate for turning in a gas mower and buying electric one, and since I do like "free money" (yeah yeah, taxes etc. Got it.) plus I was pretty heavily invested in the Ego ecosystem, so I'd decided on an Ego mower.
Here's the part you might actually care about: it's a 1200w (dual blade) self-propelled mower with a 10Ah battery and my house has about 10,000 sq ft of grass overall. (1/3 of an acre corner lot with a LOT of park strip area as well.) That admittedly large battery leaves us with about 20% of juice left upon finishing the lawn thus far (bagging the clippings.)
The mower itself is fantastic. I've actually only mowed once this year because my wife likes it so much that she actually has asked to take that over due to the mower.
So when people say "don't go over [X] size of yard with an electric mower," I tend to disagree with that. I'd argue you should say "don't get an electric mower if you're not willing to buy enough batteries to allow you to mow it all at one time." And remember that things like a rapid charger and hills with self-propulsion can change things up for you. Also, make sure it's powerful enough to cut the grass like you like it OR be willing to adapt to cutting your lawn only when it's dry or more frequently.
I think this is the exact Ego I've been looking at. I've heard it's a step above most other electric mowers, but it better be for the price. Glad to hear it's working well for you. I wish my city did a rebate like that!
Yeah, it's a shame that physics and chemistry get in the way of wishful thinking. 🙄
Bought a Toro Battery Powered Self propelled for $400 last week. I definitely will never buy a gas lawn mower again. Used it twice so far, and it cuts my lawn like a boss. I mowed the front of my house, and had 75% charge. Then I mowed the back another day, and still had 75%. It's just faster to use the new mower, because it's lighter, compared to my old gas mower. It's like a mowing Tesla. Just charge and go. No oil, no spark plugs, no air filters, no pulling the cord until you lose your mind. Just charge your battery and push the button.
Don't know too much about this brand, but I definitely recommend battery powered mowers to everyone. I live next to a motor whore, who has everything ever built to run on internal combustion engine, plus he fixes lawn equipment for folks. I think I got a noise sensitivity from it, and would not care to use anything with a motor. I'd be outside pulling the cord, breaking my back, only for it to start then clunk out. The electric mower actually makes me want to mow my lawn more often. I just push a button, and it sounds like a fan pointed to the floor. I didn't even know it was on unless I listened closely.
If you live in a 11-12 month mowing season NO.
I live in the northeast US, and I mow from mid/late April though August, or maybe mid-September at the latest. The tools and batteries I've acquired work well for me. But an 11-12 month season...I have no idea. Sounds like it might be a totally different ballgame. If you're telling me that batteries will only last two years under such conditions: I'd believe it. And maybe that gas mower makes more sense under those conditions.

1) How much does that battery weigh?
2) How much is the average lawnmowing consumer willing to pay for said battery?
I'm sure Greenworks et al. could push the envelope, but given the state of current battery-powered development, the existing "bleeding edge" (I guess 80V) seems perfectly sufficient to me. But, if you disagree - over time - it will only improve.

When I say "take care of the batteries" - don't run them down until completely discharged. At the end of the season, don't leave them outside. Keep them indoors until the weather warms up and you need them again. Give 'em a charge every couple of months while they're in storage.
If you're replacing your batteries every 2-3 years, you're doing something wrong. They should retain a usable charge much longer than that. Regarding corded: I used one of those for a couple of seasons just prior to purchasing the aforementioned B&D. It got the job done, but managing the cord made me absolutely mental - particularly since my lone outdoor outlet is nowhere near the furthest corners of my oddly-shaped yard. Never again. NEVER AGAIN.
As above: if you're replacing batteries every two years, you're doing something wrong.
Storage for longer than 60 days of no use for lithium batteries is best at 45-65% charge to prevent chemical capacity degradation.
This is why your cell phone, tablet and laptop is half charged when you open it out of the box.....
Me - currently rocking a 21" corded "push" Greenworks that I picked up five years ago. At the time I bought it cordless electric mowers did not really exist. I'm hoping to get a cordless self-propelled one this year.

YouTube it. I think they have comparisons of all the electric mowers. Including ego, kobalt, this one , Makita
