Are M-Disc Blu Rays Any Better Than Regular (HTL) Media?

The M-Disc was billed as an archival grade form of optical storage with unrivalled disc longevity properties of 1,000 years. The M-Disc boasted of doing so through holding an inorganic "rock like" layer. But if regular (HTL) Verbatim Blu Rays also use an inorganic layer ... what's the difference exactly? In this video I look a bit deeper into this question, discuss what's known about the M-Disc's "rock like" layer, look at MABL, and talk about some other archival grade optical media that's made it to market.
