I think one would need more information to make a decision here. The scope that is best is the one you can afford, the one that fits your hunting area, and the one that looks nice when you look through it. A 750 can wear any scope you want it to. Are you hunting tight bush? If so, you might want a red-dot or a 1.5x4x40. Maybe you will be taking shots of 200 yards and over and need a 3x9x40. The options are pretty much endless unless you narrow it down somehow. I personally like the Weaver Grand Slam 3x10x40, the Nikon Monarch, Bushnell Elite, and you can't go wrong with Leupold. Like I said...find out what you can spend and what your hunting conditions are.
