I have a CG63 with an Elit front sight and an aperture insert. I also shoot a Swiss K31 fitted with a Swiss Products diopter, for which I have a variety of inserts, both post and aperture. From my experience, a post front sight helps more to correct any cant in the rifle. With my post insert, I tend to get tight groups that are not necessarily in the target center, while the aperture insert keeps the group centered although not quite as tight.
