As stated they have a slick little tester that will give you an immediate answer. And it's free.
Since most batteries are so evenly comparable now we buy whatever brand has the longest non pro rated warranty period.
Last 3 or 4 batteries in the fleet here are Advance Auto, simply due to the above strategy and pricing. All have held up well...
