No doubt about it, the better batteries are expensive, mine was $200.
If you are ready for a cutting edge carbon foam based battery, there is the OASIS from Firefly. Probably $350 is my wild guess.

Do you think these are (IF they ever make them in most automotive OEM sizes) worth $100.00-$150.00 more than a Platinum/Odyssey??
For most cars, even AGM isnt worth it. Unless it is a vehicle known to be prone to corrosion, has its battery in a bad spot (trunk/under seat, etc), IMO its generally a waste. If treated half decently, the flooded battery will last nearly as long, and make the extra cost of AGM not justified.
AGM is great for applications where very large arrays of matched batteries are required, and where the numbers and intended lifecycle cause maintenance and monitoring to be expensive. Car batteries can last 5-7 years, the thermally-caused degradation reactions still occur, and they are low enough maintenance these days to not be an issue. Thus AGM is not compelling for most automotive use. Ditto for fancy doped chemistries. Volumetric/gravimetric densities arent very important in the automotive space and requirement.
