The only reasons Leupold became popular are:
A. they offered 4" eye relief back in the day when the competition was all running 3" .
B. They gained market share back in the days when nobody heard about dialing a turret. Hell, they were running friction adjust for [bleep]'s sake.
Now there are tons of better scopes on the market, but people still flock to Leupold because the one in their closet collecting dust has been "great!"
