What battery to use in my daily driver recommendations

We buy a ton of "Napa Legend" batteries for work, the last one I bought was for my 01 Durango, it has the 2 year free replacement, I had it 26 months and was told I was SOL. Zero pro rate after the 2 years. So since they wanted me to buy another one at full price (minus the shop discount that work gets) I went back to farm and fleet and bought one there. Theirs are Johnson controls, and I know that if I bring back a bad battery having used 5 years of a "7 year battery" that I will get "some" credit towards a new one.
I did later buy a battery for my other Durango from a different Napa that's a franchise owned by the same guy that has the one we use at work/ but for some reason, this store has interstate, of which I'm not a fan of either/ but considering that that battery just happened to die on me the day of my mom's funeral and showed itself just after I helped load her casket into the hearse and went to start it to follow the hearse to the cemetery, (couldn't have been worse timing/ and this Napa happened to be right next door to the funeral home I kinda didn't have a choice.)
My wife and I hitched a ride to the cemetery (only about a mile and 1/2 down the road from the funeral home) after the cemetery part of the service I went back to Napa and bought a battery and stuck it in there, then carried on to the luncheon after that.
Had i not been in that kind of a bind I would have gone elsewhere, and "not" bought an interstate battery nor from Napa. The battery that died was the battery that was in there from when we had bought that Durango (I have 2 Durango's) 9 months prior and had started just fine 3 times earlier that day of the funeral, and has started fine every day since and I have done nothing more to the starting system or charging system on that Durango since.
Why that battery decided to die that day at that time I still don't understand.
