I have a couple of the SWFA classic 1-4's, they are good for the money, ease of obtaining an image is not as good as a Leupold VX6 1-6 that had to go back to the factory as you dialed an inch and it gave you 3 maybe 4 sometimes 6. While many place a premium on big eyeboxes and crystal clear glass, its nice that the sighting device actually holds zero and you can count on it even if you drop it. My Leupold is on a hunting rifle, great application for it, just as bright in my opinion as a Victory 1.5-6 x 42 that I own. However on my serious guns its either an aimpoint or a SWFA because I have found that you can count on them to be "on". I have no idea about vortex, I am still not convinced about them.
