Its a good question and one I would say that varies.
I got a CD burner when they first came out ( man it was pricey ) and the cost of blank media was expensive so I would mainly buy discs that were cheaper or on special.
Most of those cheapie now cant be read while some of the better brands can.
Storage is a major part as you mentioned, keep them out of sunlight. And my suggestion is dont buy the cheapest out there as you get what you pay for.
