10X is great for anything over 3-400 yd. 3-9X for less.
It's true, the fixed 10X is great for stuff over 3 or 400 yards. The thing is, it's great for less than 300 too. It all depends on where you're hunting and how much cover there is.
Picking up an antelope on the prairie at 100 is no sweat with a 10X, same as picking up anything out in the open at less than 300, like a sheep above timberline.
