The discs are physically different.  Some older CD-ROM drives and CD
players had trouble with CD-RW, because the overall reflectivity is lower.
Some DVD players have trouble with CD-R for similar reasons.

Write speed can be important, but the optimal write speed isn't
necessarily slower.  The "best" speed depends on your recorder and your
choice of media.

Writing in disc-at-once mode on CD-R media is your best bet for
compatibility.  Using packet writing on CD-RW (i.e. treating the disc
like a big floppy) is a recipe for trouble.
