Can someone help me better understand:

Plex?

BDC?

Out of these two - what's your personal preference?

Sons are a heritage from the LORD, children a reward from him. Like arrows in the hands of a warrior are sons born in one's youth. Blessed is the man whose quiver is full of them. They will not be put to shame when they contend with their enemies in the gate. - Psalm 127:3-5

A plex is a crosshair, + . A BDC is a ballistic drop compensator, with dots/lines/ or circles below the center of the crosshair. This allows one to use the lines/dots/circles to accurately shoot longer distances. A standard crosshair is fine for shooting out to 400 yds, but a BDC or turret is better for longer distances. I prefer the turret style, which lowers or raises the crosshairs for shooting. Usually in MOA.

Actually a "Plex" is short for Duplex which are crosshairs/reticle that are thicker and then get thin near the center.  The thick outer lines give you fast aquisition and the thin center gives you a precise aiming point.  Once you get to know a duplex you can use the thickness of the crosshairs and the distance between the thick cross hair for range estimation.  I prefer the Plex/duplexs uncluttered image and fast aquisition on a hunting scope.

I only hunt coyotes and a Duplex is simple and there is nothing to move or change and I rarely take a shot over 300yrds so I can hold on fur  without having to change anything. KISS goes a long way on a coyote stand.
After the first shot the rest are just noise.
