I have no personal experience with Odyssey batteries so take this for what you will....
Years ago, they were considered the "best" batteries available in a lot of circles. Yes, they are almost 2x the price of normal batteries but most people considered them worth the extra. As of a few years ago, the general consensus that I've read is that things have changed for the worse with them, whether they've outsourced the manufacturing of them, maybe they're made overseas now, etc, I don't know. Have you read similar things in your research ?
I have to agree with blufeb95's points. If my battery dies unexpectedly, I need a replacement as quick as possible and if that means a warranty exchange (ideally) at a nearby auto parts store or Walmart, that would be my choice.
