CD-RW is superior. It's more expensive but you could use it as many times as you need. So if you were for example a 13 year old who loved to distro hop Linux distributions.. it's very useful to be able to rewrite whatever you were doing.
The price difference is quickly made up for with the re-usability factor.
Although I don't understand why anyone would burn a CD anymore. You can buy flash drives with a ton of storage for really cheap these days. You have all sorts of cloud options. You can even rent your own VPS for less than $5 a month.
Although they are supposed to be forever rewritable I could only ever get quality brand RWs to do 3 to 5 rewrites before burns would fail verification. Source: lots of data migration between servers where USB sticks and networking was restricted.

I don't think that's true, CD-Rs cost pennies. You have to rewrite every CD-RW 4 or 5 times before it's comparable in price. In practice, across every CD-RW ever made, the approximate number of times it is written is probably about 0.5
