Well, don't believe the hype.
Baryta Prestige has some OBAs in it, for starters. That is not a deal breaker for everyone, but its not a great sign.
Harman Baryta is a rarity with some OBAs, but still good longevity. Very few papers achieve this, maybe this is one, maybe not.
I'll stick to Platine till the longevity test results are in.
