I will take the Esco 3 ton jack stand and 24,000 lb weight capacity for four stands.
It's 10 times less expensive, almost 5 times greater safety margin and much easier to move and store.

Both of those factors of safety are more than sufficient. You have to keep in mind that the factor of safety on the item to begin with is greater than 1 so you're stacking factors of safety on top of factors of safety. Being able to lift 2x the weight with another factor of safety present is more than sufficient.
On the jack, I own both and the quick jack is starting to be more trouble than its worth. One of the cylinders developed a leak into the little pressurized air pocket part that pushes the struts back down, and you could see system fluid when you bled the little air nipple. They completely ignored my email to the published tech support email posted on their website about it and it wasn't until I contacted flyin' Miata that I finally got some help. FM told me the vendor was gonna be nice since I was just over the warranty period, and they had shipped out a replacement. The thing is the actual failure and the first email about it that I never got an answer to, were within the timeline. I still haven't gotten around to installing the replacement they sent but I probably used the damn thing less than 10 times and most of them were to lift a Miata so I don't have much faith they are going to last.
It is great to be able to hit a button to lift something and put it back down but they're a pain to move into place, a pain to store, a pain to set up and bleed, and just a general pain. It isn't that hard to use a low profile floor jack and stands so that's what I do most of the time now. Maybe one day I'll get an actual lift installed in the garage.
