I hope it's NWA 2999 as that's the only one I have of those three that you've listed. Pete" Pete, I consider all three of the angrites I have brought to the scientific and collecting world, with help from the nomadic finders and my Moroccan partners, as front runners. If it were not these angrites, many analytical testing may not have been considered. Take for instance the abstract titled "Magnetism On The Angrite Parent Body" by Dr. Benjamin Weiss of MIT in Boston. I and my most recent angrite, NWA 4931 (new 2140 gram main mass paired to NWA 2999) were flown up to MIT to have a core sample taken from this large stone. This was important because Dr. Weiss could then perform "clean" magnetism testing from a sample that was hopefully not subjected to Moroccan or other's magnets. This is a very time consuming testing process and the coring took place in October 2007. Here is Dr. Weiss's abstract, which does not include NWA 4931 because it was not yet discovered during his initial testing: http://www.lpi.usra.edu/meetings/lpsc2008/pdf/2143.pdf Here is an abstract presented by Drs Amelin and Irving reporting ages of angrites NWA 2999, NWA 4590 "Tamassint" and NWA 4801: http://www.lpi.usra.edu/meetings/metchron2007/pdf/4061.pdf Here is another interesting abstract discussing constraints for existence of a core on the APB: http://www.lpi.usra.edu/meetings/lpsc2008/pdf/1936.pdf I hope this helps you decide which is the "front runner", which may be in the scientific data each reveals or simply a matter of beauty as seen by each individual collector. All three are completely different in appearance.
