AC Delco is better than both, less than a quarter each and lasts just as long as the big brands from what I can tell: https://www.amazon.com/ACDelco-superpilas-alcalinas-AAA-AC274/dp/B00FF8KQJC/

AC Delco is better than both

Not in my experience. I bought a large package once at Menards, and several of them actually had visible acid/rust damage that I found only after opening the package. Longevity was poor. Since then, I assumed that AC/Delco sold the rights to the name for consumer dry cells to some 3rd rate operation.
