Recordable media is a crapshoot. Some discs are great, others are terrible. I wouldn't trust CD/DVD-R for long term media storage. These discs can also be harder on your optical drive. I've seen lots of Sega Dreamcast and Xbox consoles with prematurely worn out lasers because the owners mostly played burned games.
Pressed media has held up pretty well in my collection. I have CDs from the '80s that ripped perfectly as recently as last year. I've heard of discs with manufacturing defects that allow air to slowly reach the aluminum layer and oxidize them, but I have not seen this myself except on LaserDiscs.
