How do folks with actual experience using this lens regard it? Is it noticeably better/worse than, say, an 80mm Componon-S? Thanks
It is not necessarily either better or worse but it could be either. In enlarging lenses the level of magnification is the biggest factor as to "better/worse/the same" (you left out the most likely, "the same or neither") at a 11x14 magnification, depending on what criteria you are using there could/should be little, if any, noticeable difference. What can be measured is often impossible to see.
6 or more element lenses are in no way by deffinition "better" (a subjective term) than 4 element lenses of any kind except extream wide angles and most zooms. The number of elements are the guarantee of nothing.
In the world of very, very, fine lenses, one of the finest from almost every possible criteria is the Rodenstock apo-Ronor an 4 element design. Especially in the 480mm focal length. It is not just the sharpness, which is stupendous, It's the color and the amazing visual quality the lens delivers. Same for the Voightlander Apo-Lanthars, the are visual hi-fi in 3D in the hands of the very few who know how to extract the most from them. There are no slouches among the 6 element crowd that comprise the other choices. Fuji, Schnieder, Rodenstock, Kodak, and even Ilex (all of which I know) and I am sure Nikor (which I have not used) and a couple of Zeiss (which I own) lenses will all make hair stand up on your neck, and demand their owner to proclaim any one of them, the best lens in the world. (unless, like me, he is exposed to most or all of them). Some exemplary lenses are simply stunning in certain specific uses.
In most all cases, "better" or "best" is defined not by the lens or its construction, but by what it is you are doing with it. Even Schnieder or Rodenstock will tell you that in many cases a 4 element Componar of Rogonar is designed for making a 8x10 or 11x14 from 6x6, and may out perform or at least equal the more costly 6 or even 7 element designs at that magnification. The more costly lenses are intended to perform "best" at 10x magnification. This is probably true for Nikon also.
"Better" in all cases in reguard to lenses is dependent on what you are using it for. Don't let anyone tell you that a lens is by definition "better" because of how many pieces of glass are used to make it. Often they have more elements because it is easier or cheaper to make a great 6 element optic than a superb 4 element.
I own many lenses and many, many similar enlarging lenses and the is no such thing as a general rule which applies universally.
I know nobody who uses and makes images with the finest the view camera world has to offer who would reject any 50 year old 4 element Ektar, Lanthar or Ronar as necessarily inferior to any of the latest mega buck apo wiz bangs from anybody. The numbers, measurements, and MTF stuff is meaningless, it is the image you are able to make with any lens that matters. Nothing else. They are at best simple and non definitive guidelines.
When it comes to enlarging lenses, the working aperture, magnification, diffraction, enlarger alignment and quality of the light source have a greater effect on the subjective "better" than who made the lens or how many elements it has.
Enjoy your 75mm El-Nikkor, for your use it is almost perfect, just like any other choice. Compared to 80mm Componon-S (of which I own 3 and a couple of 5.6 Componons too) it is "better/worse/the same". It is cheap enough to own both.
To be totally honest with you, I have long wondered what is the bias against the 75mm Nikkor, just like you. Then I realized that there is a huge community who reject certain Leitz Leica lenses based on what country they were made in. That is simply crazy, and makes no sense whatsoever. As a long time Leica user, I know empirically, NOTHING is more madcap than that.
