I would say the square wave played on the CD player is technically superior. It is essentially a perfect square wave in the sense that it is mathematically perfect for a 1-kHz square wave that is truncated after its 21-kHz harmonic and displays virtually no high-frequency phase shift with only very slight low-frequency phase shift due to capacitive coupling.
Here's the square wave from my CD player:
Here is a truly mathematically perfect square wave truncated at the 21st harmonic, which would be equivalent to a 1-kHz square wave with its final harmonic at 21-kHz:

Here are all the square waves from a phono cartridge playing a test recored:

Regardless of which square waves you feel are more technically superior, 16/44 CD digital is basically obsolete nowadays. We have higher resolution digital formats and most new albums are recorded in those higher resolution formats. Square waves reproduced by higher resolution digital formats would still be mathematically perfect with even higher harmonics yielding faster rise times with flatter tops and bottoms.
