One may argue that some of the performances may not be the best performance of that particular work, but even conceding that (which I'm not necessarily prepared to do), there is no arguing with the consistently high quality throughout this vast, complete collection of Beethoven's compositions. Further, knowing that it's all here, well-packaged, well-organized, and that you have missed nothing, is quite a valuable consideration. You don't have to buy your fourth copy of the fifth symphony because it also contains the only available recording of something you are missing.
If one intends to build a significant music library, this is a major building block.
