I have been wondering the same question. I have done some research on the both of them, on their websites and various videos on YouTube. I have also got the input of several fellow marines, including sniper instructors. The B.E.A.S.T. has the well known NightForce look, beautiful turrets and design. If i was going to buy it over the Vortex for any reason it would be for looks. I do not like how they made the adjustments in sets of two, and then you have the throw lever to add the extra .1 MIL or 1/4 MOA. I hate that, if it wasn't for that I would buy it. I do however like how they integrated a button to change the illum. Both scopes appear to have incredible glass according to reviews from customers. But the Vortex in my opinion is ugly. I hate the color. If I do buy it, it won't go with FDE or black. I honestly don't know why they wouldn't have different color options if they wanted to have that bronze color. I'm not a big fan of the design of the texture of the turrets, i would much rather prefer NightForces large, aggressive grip. But Vortex knocked it out of the park with function. The locking mech is amazing and simple. The B.E.A.S.T.'s locking mech looks like you could rotate the elevation while trying to lock it, and the windage will lock at zero, but you cant lock it after you have dialed in your dope. That doesn't make sense. The Vortex also has a pretty cool way to adjust the illum by pulling a knob out of the parallax turret. I want to buy the Vortex, for (1) to save money and (2), because it appears to be easier to use. But I already know that will hate how it looks. If i had the money to blow, I would go for the B.E.A.S.T. because it is sexy, and it would help with the resale value of the rifle.
