Having slated Leupolds for the past 12 years or so, I recently purchased a MK4 8.5-25 x 50 and I have to say I am as happy with it as with my big Zeiss and Swarovski. I love the reliability, functionality is a small and lightweight package. The optics are very good indeed. I have used it at 1000 yards and long range varminting too. I rate them highly.
