I have to say I find the arguments made for and against any type of hunting gear to be very similar, regardless of what type of gear we're talking about.
The best of anything is typically the most expensive. Not always, but as a general rule, you can count on that. In terms of binos, that means that Swarovski, Leica and Zeiss are the most expensive. They are the best, so they get to charge the most, and they do.
But that shouldn't be the end of the discussion for binoculars, or for any other type of gear. Identifying the best of anything is typically pretty simple. Identifying the best value in anything is much harder.
By that I mean that while a $2000 pair of binos will almost always be 'better' than a $1000 pair, will they be twice as good? Will they be 4 times as good as a $500 pair? While it's possible that the answer is yes, I'd suggest that most likely the answer is no. The nature of the beast is such that you pay ever increasing increments for ever smaller improvements.
If you have the means, and you don't mind paying the price, by all means, go ahead and buy the best. Otherwise, you have a tougher decision to make.
Typically, and I believe in binos as well, there will be a lower range where it can be clearly said "you get what you pay for", and not in a good way. Eliminate those; they are no bargain. To quote a tracker I heard in Ethiopia once "nice price buy twice."
You're now left with a range of binoculars between those at the bottom and those at the top. This is where most of the good brands are, and where most people will generally be satisfied with their purchase. For binos, this range is generally from a few hundred dollars to less than a thousand. Within that range, you will find many binos that will do almost everything the best will do, but perhaps not quite as well. So go to an outdoor store, tell them you want to look at hunting binos, tell them what you want to spend, and test a bunch. I believe you'll find that all are pretty close in terms of viewing, but differ in terms of comfort, fit and finish. Buy what feels natural in your hands, and what allows you to get a good picture the quickest. I believe that any binos in this price range will last as long as the best, which is to say, they should outlast you.
I believe that if you do this, you will have the best value binoculars, which are those that do everything you really need them to do, at a price far below what you would pay for the best.
When I was much younger, and I had many more claims on my dollars than I do now, I used Leupold scopes. Now that things have changed a bit, I use Swarovski. Are the Swarovskis better? Sure they are. Are Swarovskis so much better that you'll be a better hunter? No. Same with binos.
