I have used a Nikon and a Bushnell, and the Leica is hands down the best. Under nice calm normal conditions they all will suffice, but when you have poor visibility, like rain, snow, fog, haze (varmint hunting) or breezes that blow the bushes sideways, the Leica rises to the top. Also on dim non-reflective targets at maximum range, the Leica will outperform all the rest. Did I also mention that the Leica has optics that are second to none, and that the battery life is 50% longer than the competitions? Good.....I would like to mention that now..... I own a Leice 1200, but that does not change the facts...It costs more, because it is more....
