I have one very old Leupold and it is a fantastic scope. It has never let me down. Now I use Nikon Pro Staff scopes on two of my muzzleloaders and I really like them. They have great glass, excellent clarity, light gathering, and seem tuff as nails. The Omega is considered a better class then the Pro Staff model. And the Nikons are less money then the old Leupolds were. Now some of the new Leupolds that are hitting the market are competitive in price to the other scopes. But I do not own any. I have heard a lot of good things about the Leupold Ultimate Slam, Nikon Omega, and Bushnell Elite all of them being good scopes. Which is better? I am the wrong person to ask.
