I used a $30 cantilever mount from Ebay to put a Tasco 3-9x40 scope on a 6.8SPC2 upper that I bought for whitetail deer hunting. It may not be the high-dollar perfect rig, but I bought all of it for deer within 150 yards, so the zero will hold better than I can aim at that distance, and I will NOT remove the mount without rezeroing, as this has a strict purpose. This setup has worked well for me. If I were setting up a platform where I was switching out optics on a regular basis, I would invest more in it, to assure the return to zero capability. So, I guess it would come down to what you intend to do with it, at what range, if you will be swapping optics without rezeroing, and what your budget is, but close-range work without changing optics, I doubt you would see a whole lot of difference for the price, except as applies to the finish (my Ebay mount finish isn't pretty, but it is for hunting, not impressing others).
