My experience is somewhat limited, but I have used the Dickson style and genuine Multifix casually. The Multifix is indeed better than the Dickson, but so is the wedge style Aloris system. The Aloris always uses the same side of the wedge as the reference surface for side to side clamping. In and out reference is provided by the flats on both sides. The movable wedge serves to pull the holder onto the post AND to pull the holder down to locate the vertical reference established by the adjustment screw. This downward force is in my opinion the single biggest improvement over other systems which rely on gravity or the operator to provide this force.
