I'm thinking so too. Bill's Battery, a local long time battery distrubuter in my area has always offered Delco as the top of the line battery.
Always has at least 2 battery choices, Queen City Battery or the Delcos. Delco is always higher priced and has a better warenty.
I have also heard many guys say that Interstate is a good battery.
I do know now from the last 3-5 years of buying some Car Quest batterys, they don't last. And I judge that by buying about 6 a year for the last 3 years or so.
