I favor the Leupold, although many other mid-range priced scopes have improved in quality in recent years.
As far as magnification, there's little real need for much over 4X inside 300 yards, if one's main use is deer hunting.
I like the 3x9, for benchrest load testing and "just target shootin'", or for varmint shooting...
Like dakotasin, many like a 6X. My father had one on an '06 for decades. Dunno positively why, but I've always felt the 6X was sorta betwixt and between. Less field of view than the 4X; less power than the variables with 7X to 9X capability. Tossup, I guess...
FWIW,
