You won't see me do a comparison as that is not how I do it, it's up to you to make the decision on which one you want to go with.
I will lay out my observations, and you can decide. The specs' are published as far as reticle thickness and what they look like. The schematics are online from most manufacturers showing what to expect.
I know my Mil / Mil BEAST is supposed to be on the way, once I have it in hand I will details my experience using both the MOA version and the Mil version of the same scope. How it stacks up to a S&B, or Premier, or Vortex, or Kahles, is a matter of opinion, it's a personal choice.
I happen to find the BEAST to be an excellent scope, and I have said this numerous times. I really like it and plan on running it on a consistent basis. If that doesn't tell you something, nothing I say will.
if you have not pre-ordered a BEAST already, the odds of you getting it before the summer will be slim. The ones who pre-ordered them should be seeing them soon. My last estimate based on numerous conversations was, first shipments to dealers for pre-orders should be heading out the door in March. Once the pre-orders are taken care, which I suspect will be some time. After all they stopped them because so many were coming in, then everyone else will have access to them. If you are lucky enough to find one where the pre-order owner decided not to wait, good on you. You scored.
But the reticle, glass, the adjustments, the size, the weight, the feel, the use are are excellent and in my personal opinion stack up to anything you might want to compare it too.
