The nozzle these two machines shipped with, so fitting it changes nothing about how your profiles behave — it simply restores a worn one to the flow it had when new. Brass moves heat well, which keeps the melt zone stable when the machine is pushing material quickly. Nozzles are consumables, and a gradually widening bore shows up as blobby corners and dimensions that creep before it ever shows up as a blockage. Cheap insurance to keep one in the drawer.
