The difference between the eye relief in the two newer Aimpoint magnifiers is very small, and I haven’t noticed a difference in the glass at all, so the price difference just isn’t justifiable for me with that mount.
If you are going to go scuba diving with it or be extremely rough with it, the 3xmag-1 is more water resistant and supposed to be tougher.
The only other small advantage the 3xmag-1 has is that its flat on the bottom so you can use the buis in the unity mount underneath it. The 3x-c is round and blocks the sight so has to be removed for that.
