Steiner > SWFA any day and twice on Sunday.
A milrad reticle in a 1-4 LPVO is mostly a gimmick. These aren't precision sights. They are minute of torso sights.
The Steiner reticle is minute of torso with both 223 and 308 common loads all the way to 500 yds. Not speculation, I have a Steiner 1-4X P4Xi and I take it to distance.
I also have a Steiner 4-16X56, SWFA 16X42, and a SWFA 3-15X42. I won't be buying more SWFAs......
