Pressed discs are much more archivally (not sure if this is a word) sound. Burned discs only have about a 5-8 year lifespan pressed discs can last much longer to the 15-20+ year marks. I do not know of a shop, but usually when you do pressed discs you cant do a few its usually like getting a 100+ disc batch, but that information is likely outdated. the main difference between burned and pressed discs is that pressed discs actually don't have much of a dyde but more of an etching process burned/RW discs have a dye that reacts to air and light. and interestingly the lexan that's commonly used is gas permeable. I know this as right now the museum i am working for is running into large scale archival solutions for video/audio that does not have a lossy result.
