There is a lot of conversation about the scopes with the best glass and tracking but rarely do we hear anything about Field of View and the Eyebox. What are the opinions out there on scopes with the largest FOV and Eyebox?

I think that's a really open ended question because you didn't specify a mag range so for example a 1x scope of quality will obviously beat any 3x scope and a 3x will beat a 5x etc. is there a particular range you are looking at?
Covert is as Covert does.
Plenty of good feedback on the scout site.
I did some looking into spec awhile ago in different mag ranges and among a few brands, I found vortex to have very good field of view in the viper and razors, also found nightforce shipped to have a little lower field of view, also have owned and used various scopes from both, viper hs pst razor, nxs and atacr. Take this with a grain of salt, but to me scopes with the same mag range with larger field of view are easier to get behind. Just my opinion.
I actually found the opposite. While the Vortex Razor Gen 2 eyebox is sweet, the PST line has been...... ehhh. And the PST Gen 1 1-4x eyebox AND FOV was pretty subpar compared to the Burris XTR 2 1-5x. But assuming we're talking about bigger rifle scopes, I've found it goes PST Gen1 < XTR 2 < PST Gen 2 < Razor series. That's only based on what I've heard. I've only looked through the Razor, PST Gen 1 and XTR, but most people are saying the PST Gen 2 glass, eyebox, and FOV is nicer than the XTR. Also IDK where Athlon fits, the Ares aren't out yet.
Well if you're talking about scopes in the 5-25 magnification range then it's hard to go past the Minox ZP Tac and the Kahles K624i for eyebox and FOV.
Yeah, the size of the exit pupil (among other things) contributes to how big or small the eye box is. Another factor is your own eye's pupil size at any given time (it changes depending on viewing conditions and one's age).
From: https://en.wikipedia.org/wiki/Eye_relief
"The eye relief property should not be confused with the exit pupil width of an instrument: that is best described as the width of the cone of light that is available to the viewer at the exact eye relief distance. An exit pupil larger than the observer's pupil wastes some light, but allows for some fumbling in side-to-side movement without vignetting or clipping. Conversely, an exit pupil smaller than the eye's pupil will have all of its available light used, but since it cannot tolerate much side-to-side error in eye alignment, will often result in a vignetted or clipped image.
The exit pupil width of say, a binocular, can be calculated as the objective diameter divided by the magnification, and gives the width of the exit cone of light in the same dimensions as the objective. For example, a 10 × 42 binocular has a 4.2 mm wide exit cone, and fairly comfortable for general use, whereas doubling the magnification with a zoom feature to 20 × results in a much more critical 2.1 mm exit cone."
From: https://en.wikipedia.org/wiki/Exit_pupil
"A set of 7×50 binoculars has an exit pupil just over 7.1 mm, which corresponds to the average pupil size of a youthful dark-adapted human eye in circumstances with no extraneous light. The emergent light at the eyepiece then fills the eye's pupil, meaning no loss of brightness at night due to using such binoculars (assuming perfect transmission). In daylight, when the eye's pupil is only 4 mm in diameter, over half the light will be blocked by the iris and will not reach the retina. However, the loss of light in the daytime is generally not significant since there is so much light to start with. By contrast, 8×32 binoculars, often sold with emphasis on their compactness, have an exit pupil of only 4 mm. That is sufficient to fill a typical daytime eye pupil, making these binoculars better suited to daytime than night-time use. The maximum pupil size of a human eye is typically 5–9 mm for individuals below 25 years old, and decreases slowly with age"
