Formidilosus, if a person is on a forum asking about comparing binos and creating a conversation about it then I would say he wants to know what those differences are. Wether they are a functional difference to you is one thing and wether they are a functional difference to someone else is another thing.
I use alpha glass. If someone has to hang a newspaper up in low light to see a difference between glass…. That is picking flychit out of pepper, as it were. He asked what he was missing, that’s the answer- there isn’t much.
The guy is trying to get the best bang for his buck. Trying to get the best quality for the money he spends is the best functional difference for his dollar.
Swari NL Pures are not the best bang for anyone’s buck. They may be the “best”, but you are paying heavily for a very tiny fraction of improvements over others.
Comparing which bino will perform the best as it gets dark is a great functional difference for many people. You may get an extra 10 minutes of glassing late in the evening or early in the morning. In areas that get a lot of hunting pressure sometimes those nocturnal animals come out right at dark and a sub par optic sometimes will not see it.
Of course. But one doesn’t have to tripod mount binos or read fine print to see the difference, if they do, then there isn’t a functional difference between them except for the most extreme scenarios.
I cant tell you how many times I've seen people talking on these forums about getting an extra 10 or 15 minutes of glassing in the dark. Some people squeeze out every second. I love a good debate so please feel free to give opinion. Fatrascal.

They talk about it, but how much of that is legitimate, objective comparisons, and how much is confirmation bias?
I’ll give an example- Swaro 15x SLC HD’s are widely regarded as the best 15x on the market. Meopta B1 Plus are said to be really close, but not quite as good. We had three people on a mountain glassing for quite a while going back and forth between them, all three preferred the Meoptas. The only thing the Swaro had on them was the very edge clarity was
slightly better, and FOV was a touch better. However in every other sense- resolution, clarity, brightness, color, etc. the Meoptas were preferred.
I have done the same thing with quite a few people that use glass, but don’t care about brands. They don’t care if it says Swarovski, Leica, Zeiss, Meopta, Hendsoldt, etc etc. Almost to a man they have preferred the Meopta over the Swaro 15x’s.
People say they see lots of things, almost always because they’re “supposed” to.
