It is legal to copy any music to a tape since tape manufacturers pay royalties per foot of the tape. Same is the case when you copy to "Music CDR", that is slightly more expansive (because of royalties) than plain CDR.
As for copy vs original sound - copy might sound better since ripping software can read the same sector multiple times. CDP cannot do this, working in real time. Samples under scratches (along the track) will be: <4mm will be auto corrected, 4-8mm interpolated, >8mm lost. CDP might change the sound by interpolating a lot of samples on scratched CD. By ripping you can "refresh" scratched CDs. On the other hand CDR and CD might behave differently in CDP (different reflection) while computer servers might introduce jitter.
