I like the Burris out of those three. They have slightly heavier internals and lenses and I think that makes them a hair more durable, though I have no way of proving or quantifying that. I also find that the Burris scopes have a better "feel" to the eyebox when you look through them. The black ring that you see a little of, even when the eye-relief is properly set, seems smaller with the Burris than with other scopes. Maybe that's just the way I see it. I have a Signature 3-9x on my 30-06 Stevens and a Fullfield II 3-9x on my 25-06 custom A-Bolt. Both are great scopes and I'd buy either one again. I am a fan of the 2.5-8x VX3, but that's a big step up in price from what you're looking at.
