I recently asked the same question in this and other forums, and the Brookfield and McCann were the most voted, with the Spring. 3erd. Gen. a distant third place. I don't know about the Brookfield, but McCann there is a little gunsmithing needed to install the mount. Because of this and the much lower price I went for the Springfield, I mounted a Tasco SS 10x42 on Spring. 30mm rings, and have no regrets. The mount is very solid and the scope has been excellent in every aspect so far (about 800 rounds fired). As all the other mounts is see-through and very high, so you'll need a very high cheekpiece to properly align the eye.
