Eh, overall R for the same reason most peeps have said, it was pretty much guaranteed compatibility.

But truth is, RW worked in anything I ever tried it in, and it was nice for having a couple of car discs full of mp3s that I could shift around some. Since I have a small case of those in the car that still work, I ain't mad at RW at all. It's been eight years for some of those, and over a decade for two.

I should probably order some and make a few new ones lol.
