I like the 3X9 but prefer a little more magnification for target work. The VX2 4-12 AO fine duplex is a great compromise in size, weight, and magnification if you shoot as much target as hunting. If you hunt more than target shoot, I would go with the 3X9 EFR.
The 4-12 AO will focus on 12X at 20- 25 yards and closer on lower power. A Weaver V16 is another good RF scope but a bit larger and heavier than the Leupold 4-12.
I'm with R H Clark on preferring more magnification for target shooting, but do have the 3-9X EFR on a 10/22 carbine. It's a great scope to put on a compact rifle for general plinking or varmint work around the house.
