Odyssey has always been a really good battery in my experience, though in any big industry like the lead-acid battery industry, there's always shuffling and consolidation going on among the various manufacturers and investment groups. It used to be Hawker Energy, then I think Enersys bought them out, nowadays I'm not sure who owns them. I used to run all Hawker batteries (Sears Die-Hard Platinum series), but since the decline of Sears I've been running the DEKA/East Penn Mfg Intimidator AGM batteries with good results.
I see a lot of people hype up Interstate batteries, and I understand why, but just for the record, they don't manufacture anything. They're an engineering/distribution company the basically pays companies like East Penn Mfg (DEKA), Johnson Controls (JCI) before they sold their battery division to Clarios, Exide, Enersys, etc., to manufacture their batteries under contract, so it could be one manufacturer one year and another the next. There's also a regional component since shipping batteries is expensive. If you've ever been in a battery plant and walked through the final assembly lines for the batteries, there are stickers for all sorts of brands you'd recognize from all of the major OEM's, to the aftermarket stuff for Napa, Autozone, WalMart, etc.
