I only have 2 Leupolds, VX1 and VX111. I prefer the Monarch to the Leupolds, I also prefer the Bushnells to the Leupolds. One thing I hate about the Leupolds is the varying eye relief at different magnification. IMHO, the Monarch, 4200 and 6500 are all brighter and sharper than the VX111. I like all of them,don;t get me wrong but I am not sold on the Value for money aspect of the Leupold.
The 6500 I really like. In truth the 4200 is a little clearer. I bought the 6500 as I wanted a versatile scope, 2.5/16 is versatile. It is an excellent scope as it should be for $580. I might have been better buying two 4200's but I do not regret the 6500.
