These are the best spotting scopes money can buy. You get fluorite lense elements, virtual elimination of chromatic abheration, bright clear views of any target. We'd be thrilled to own any of them.
As with other range topping categories choices at this level are subjective, largely down to personal preferences. Kowa is the category inventory, Swarovski, Leica, and Zeiss have all made incredible, uncompromising spotting scopes too.
There are no bad choices here, no compromises either. Some if the key considerations you'll want to keep in mind are weight, dimensions for travel, and what you'd like to use for an eyepiece. These all offer choices so that you can tailor the scope you your personal needs and tastes.
