It depends on the hunting you do. Most medium game hunting is whitetail from a stand. My experience is binos are only useful in the very few minutes of legal light where you can see with good binos, but not naked eye. Binos are glued to my eyes at those times, but I do not use them otherwise Using them in good light seems to alert older deer which look for movement in stands and reflected light in general.
People like to argue that you shouldn't look at deer through the scope. That's silly because you're sure it's a deer before you point whatever you're looking through at it.
Other hunting, binos are more important than an upgraded scope. Most other hunting, I'd be fine a with Filipino scope, but I wouldn't bother to carry the same quality binos. I'd just do without.
