The sonic quality of both formats has the potential to be superior to CD, but the recording and mixing of the particular disc is very important. Some CDs sound better than some DVDA, but this is not the general case.
The most valuable aspect of SACD and DVDA is their multichannel capability. Properly implemented (which is often not the case) multichannel is a giant leap forward. Unless you can swing a good multichannel system SACD and DVDA may not be worthwhile.
