From all the checking I have done in the past, the quality level is exactly the same with these batteries.
Mine are "Pro Series" from Battery Outfitters. I only got those because Sams Club didn't have 3 of the battery that I wanted, only two at the time. Two years old now ( maybe older). Last year, they went dead multiple times over the course of a couple months while the mechanic kept leaving things on and letting them die. Never quite had the same starting power after that, but over a year later, they still work pretty well. They get a pretty good workout in my truck as well as I do all my cooking in here and usually leave the fridge stocked and running even when I am out of the truck for multiple days. Never idle the truck, so in the cooler months, the batteries constantly cycle down to the point where the APU fires up to recharge.
Only 3 batteries in my truck, so i went with the 950cca because Detroit recommends 2700 amps to start the engine. I would use the smaller 700's if I had four batteries.
