Up to now I have been using only DVD-Rs to backup my data, but lately the only Taiyo Yuden discs that I can find here in Spain are Fuji DVD+Rs, which prompted me to wonder which of these two formats is more reliable. I've searched for the FAQ, but didn't find any definitive answers, and I've read lenghty articles here in the forum in favor of both formats (just right now I can see a thread from a few days ago with a post saying that +R is better).
My main question, beyond all that, though, would be: does it matter that much? Suppose one buys Taiyo Yuden media and stores it correctly (no extreme temperatures, no sunlight, etc.)... will the +R/-R factor make any difference at all on whether the disc will still be readable in a couple of years? Or is it one of those splitting-hair things that don't really matter in the big picture?
(My current DVD-ROM is a Lite-On, and can read both formats, so I'm assuming that isn't a factor).
