The NEB is a historic Beckey route. The N rib is a Lowe route and the story of the FA is much less dramatic.
The NEB is a more visually appealing line from a distance. The North Rib is pretty ill-defined from most angles, and the NEB is this huge fucking prow.
The N Rib is a rock climb on a north face which means shady, cold and often wet. Takes longer to come into condition.
Finally the north rib has the escape a couple pitches from the summit when it crests below the final summit tower. Whereas NEB goes straight to the summit, no weasel-out.
