I guess I like the simplicity of a fixed power scope, and it just stands to reason that with fewer internal parts their is less to go wrong. Other advantages, constant eye relief, the same no matter what. Less chance of the Magnum eyebrow, since the eye relief is normally greater on fixed power scopes. Shorter Eye Bells on the Eye piece (ocular lens). helps on the mounting of a scope, also assist on lesser chances of the Magnum eyebrow gash. Smaller profile of the scope seems to let the rifle glide out of a scabbard allot easier. Lastly for the people who claim the cross hairs of a 4x scope cover the whole deer at 400 yards, they need to look at Leupolds Reticle Subtension chart ( a 4x fxII scope thin section of the reticle is .8"@100 yards=3.2"@400 yards). So if you can't hit a deer at 300 yards with a 4x scope, it's best to look in the mirror, and not at the 4x scope. whistle
