Often, the 1moa dots in the circle-dot reticles are more defined. I’d agree the Sig/Holosun stuff seems cleaner than others. I like LPVs, but have some prisms that are good, as well. Personally, I feel I’m as fast and accurate with a trijicon 1-4 and their triangle, as anything I’ve used, issued or bought. My little VX2 1-4 w/ German #1 ain’t no slouch, but it’s not illuminated.
