Bob, just for my learning process, I checked the technical information.
It is true that the G performs a bit better than N (in the graphs) when both are wide open.
But in part this is because the N is one stop faster, graphs show the N at f/4 and f/8 while the G charts are at f/5.6 and f/11
Of course charts are for each lens at suitable ratio, x6 and x20.
Probably the N would perform close to the G if the N was stopped to same f/5.6, guessing from the improvement we see for the N when stopped from f/4 to f/8...

I find those graphs interesting to learn what happens when using an enlarger if a demanding job is course. I find it's not easy to interpret how performance in the graphs does impact in the print quality, but that information should be useful when trying to improve print quality, that's what I feel...
Probably G or N lenses had another contributing factor... people purchasing that kind of gear probably weren't rookie printers, and probably they knew how to make a sound print.
