I am having some trouble discerning the better digitization of these three typefaces.
There do appear to be some differences in them, not withstanding the face that Linotype Univers and Univers Next offer a far greater number of weights than Univers, as well as the more desirable ampersand; the cut (so to speak) appears different. Both Linotype Univers and Univers Next seem to have more modulation in the strokes, and Linotype Univers 430, which I assumed to be an equivalent to Univers 55, seems, well, heavier!
Also, any idea which is closer to Frutiger's original design?
Any help appreciated.
