Both are inert gases. Either will work fine as long as the seals hold the gas where it is supposed to be......... inside the binocular.
Argon is much heavier than nitrogen. Don't think with the small amounts used that it would make much of a difference on weight of binocular.

In theory, as pointed out above, Argon is heavier than Nitrogen. It is also heavier than Oxygen. Theory being that in case of seal failure the Argon will be less prone to diffuse through the faulty seal into the atmosphere than Nitrogen would be. In practice, I doubt there is enough difference to tell about.

MINOX uses Argon gas and they are not all in the "lower priced brands", far from it.

Not sure on cost these days, but at one time argon was higher than nitrogen. But then again, with the very small amounts used in a binocular, the gas price probably does not come into play.
