That has not been my experience at all. I think Kirkland batteries have less capacity than the premium brands. Also the point of lithium batteries is that they don't leak, not that they last longer.

If you're comparing alkaline to alkaline, it's simply not true. The two videos I linked showed people testing it.

Well, they DO last longer by a significant margin. Again, this was tested in the second video I linked. The description in the video has a link to the spreadsheet of their data: https://docs.google.com/spreadsheets/d/1KwTt0lu7_aytity4IE3S...
Kirkland Alkaline was on par with the Rayovac Fusion+ and Duracell Powerboost. Only Rayovac Fusion was noticeably better (oddly, the non-plus version was better), and even then, it's not significantly better considering the price.
In terms of dollars per mAh, Kirkland is #2, only behind AmazonBasics.

Not leaking is part of the point, but it's definitely not the only point. Alkaline batteries have half the capacity (roughly) compared to lithium cells. They also have lower voltages over time vs. lithium cells and are capable of less current. For certain applications (high current draw intermittent, or long life low current) they excel, and leaking isn't really part of that conversation.
