I think they would have the same lightfastness.  In Eb1400 a single HP Z3100 PKn or UT14C (also a PKn, slightly cooler than the HP) is used.  In the Eb4+ mix the lighter (more dilute, LK) versions of these neutralized PKn's are put in the LC position.  For any given print tone I think the same amount of color pigments would be used.  So the reduction in longevity relative to 100% carbon would be essentially the same.

The Eb4+ -- http://www.paulroark.com/BW-Info/Eboni-4-Plus.pdf -- is going to be smoother and easier to profile where you want cooler prints.
