Funny i have been debating the same two scopes, the euro has one less lens that the old black diamond due too the lack of ao which makes it a bit brighter according to burris, i like the fact it has the ballstic plex where the nikon does not! the nikon is sweet though both weigh about the same and have same amount in eye relief, all i can say jon at optic zone has the best price i have seen on these
