If you want top quality binos, buy Leica, Zeiss or Swarvoski. If you don't want to pay top dollar, Nikon is pretty good too. I learned a long time ago that quality optics will save a lot of walking and a lot of time. They are worth every penny they cost.

I personally carry Leica 10x42s for the majority of my glassing if I'm walking. If I'm sitting I use a 36x Swarvoski spotting scope. If I'm in heavy cover I use a 10x28 pair of light Nikons. I consider them all of them to be vital to my hunting.
