Dunno, but when the paper cones were introduced the early results showed slightly higher distortion in the midbass through lower mid range region compared to the aluminum. Haven't looked at those results in a number of years though, different sizes might behave differently.
For does who cannot wait for the English version to be published, like me, here is a google translated version.

"D"is my favorite versionAll seems to have their strenghts and none seems to be best on all things. To me when all things considered Diamond is the best of the bunch
Guess again....
The phase plug is an aluminum shorting path, but there is no copper in those aluminums I've taken apart.

Off axis response is similar.
The big difference will be in harmonic distortion. While at 2.83 V the textreme is only marginally lower in distortion, sound output at 2.83 V will be much much higher since it has a sensitivity of 96 dB. Therefore, for the same volume output it will be using a lower voltage along with the associated lower voltage distortion curve.
Basically, it'll play way louder despite having a lower rated power.

Not sure it is the best, it depends on your personal preference, but it has the lowest IMD between them and very good sounding too. Highly recommended.
