The erectors on Leupys are definitely from another era and about half the scopes I've sent back for work end up getting an erector replaced which I didn't even know was bad!!! Ie I send a scope in for a new reticle and it comes back with a new reticle and, for free, a fresh erector. But as Old Crab said, if you're going to set it and forget it, they tend to work and work for a long time.
All the $1000-$2000 scopes definitely have way way better erectors but they also weight 2-3 times as much and also cost 2-5 times as much. For light rifles I still use Leupold, I just make sure to use them a bit before I plan to take them hunting. For scopes I dial a lot, no, don't use Leupold, but that also mostly applies to Swaro.
