I have DURALAST in my BURB, but I am less than thrilled with them. The wifes car has a CARQUEST battery(DEKA) in it, and it seems to be a much stronger battery.
Interstate Megatrons less than 2 mo old in the truck to replace the (suddenly) dead OEM.
Tahoe has a 1 week old Interstate Megatron that replaced the (again - suddenly) dead OEM.
The tire and battery shop I trade at is about 1/2 mile as the crow flies from the farm. Very convenient.
The truck has one from TSC(no idea who makes them) still surviving after 8 years of hard use. The van(wife's) has a Canadian tire brand one. can't complain at the CT one, it's got a 10yr warranty free replacement.

2004 Yukon XL 2500 - ACDelco from my diesel
1995 K1500 'Burb - ACDelco from my diesel
2004 Honda - Advance Auto (whatever that is) stole from my K15
I used to swear by a DieHard, but now IDK. Besides, If I leave a battery at home while I'm away it might get "borrowed" so I just get the most CCA for the least now.
I have two Interstate Megatrons (not a evil Decepticon) that are 12 years old and still will crank my 6.2. They have been serving in two different cars since the truck is off the road. Tired yes but still serviceable.
Kirkland (Costco brand) in both trucks. Two in the GMC, one in the Dakota. Made for Costco by Johnson Controls, same company that makes a lot of the big name batteries already in the poll.
The one in the Dakota is about 6 years old now, still going strong. The two in the GMC are two years old (replaced as a pair).
