Yes. At least for audio IMHO. But it's not worth buying the program just for its CD burning capabilities.
I use Wavelab for "mastering" my projects, and therefore it is simpler for me just to burn directly from Wavelab once the files have been mastered, rather than to have to export to another program. It also provides the ability to change sample rates and/or bit depth, and includes the Apogee dithering algorithm.
As for CD burning itself, I think Wavelab gives you better control over track spacing, it allows for cross-fades between tracks, as well as the ability to set markers for new tracks wherever you want. It also can do the "mixed" type CD's which can have audio and data on the same CD. Further, it has a meta-normalize function which purports to equalize volume across all the tracks of a CD (FWIW I don't use this feature, as I prefer to rely on my ears, and I also don't think it really works too well - but it could be due to operator error.)
As stated, I wouldn't purchase Wavelab JUST for CD burning, though. Particularly if you already own EZ CD, or Nero. And it's a bit on the expensive side. However, if you are looking for an all around program that can handle mastering, wave editing, AND CD burning, it's a great package.
