There is another issue to consider: I store my DVDs in tyvek sleeves. Tyvek's great, but the window is smooth plastic. I've discovered, to my loss, that shiny silver discs are so smooth on the "label" side that they can stick to the plastic window after being stored for a couple of years. When that happens, it's very easy, when removing the discs from the sleeve, to pull the label away from the aluminum layer, destroying some or all of the data on the disc.
I've never encountered this problem with discs whose labels contain printing, white paint to accomodate your printer, etc. Those are just rough enough the window doesn't stick to them.
If you might store discs in sleeves of any composition, I'd recommend you go with discs that have something printed on the label side. Whether it's a bunch of branding junk or white for printers doesn't matter: only that something is printed there.
