I never have looked through a pair of Swaro's or Leica's as they have always been out of my price range and I didn't want to deal with the temptation. However, Last Fall I purchased a pair of Leopold Katmai binocs after comparing them to others in the $500 price range, and they are the best I have ever looked through. I have a pair of 8X36 and they are very compact, very bright, very clear, and fairly light weight. Just perfect for whitetail hunting. And they have a pair of 6X36 that would be even lighter if you didn't want that high of power.
To top it all off, I payed less than half of that $500 for a display model that I found online. That's just my 2cents, but if you can afford top of the line then go for one of them.
