I like Exides for value for money compared to Bosch etc, but I've not really had a car long enough to see how good they are for longevity.
Last battery I bought was some unknown brand on eBay and it works fine.
I don't know specifics but a lot of the common brands these days are whacked out by the same factories, to the same design with some minor cosmetic differences and a different label - with identical performance and longevity when comparable specs.
Even a lot of the lesser known brands are the same batteries just not A grade parts.
