Dual/Double Layer discs are harder to read than Single Layer discs, so it follows that damaging a DL disc so that it cannot be fully read is easier than damaging a Single Layer disc beyond readability.
Since the mechanical structure of a DL disc is more complicated than the structure of a Single Layer disc, it’s also possible that this could make it more susceptible to deterioration over time - but that’s mostly speculation on my part.
There are special “archival grade” Single Layer discs, but no special “archival grade” DL discs to my knowledge.
If you want the least risk of something bad happening to your archived data, I suggest you use Single Layer disc of high quality.
But it’s possible that DL discs may be “good enough” for your purpose.
