We have several too-notch spotting scopes, including a Leica, Meopta, Nikon Fieldscope II, and Swarovski. They're all excellent, and the only practical difference between them is the size/magnification (and hence the application) of each of the scopes. Have used all of them enough in the field to know you probably wouldn't miss seeing something with one and not another--except perhaps in really dim light, where the 75mm objective of the Meopta makes a slight but noticeable advantage over the somewhat smaller objectives of the other scopes.
