I've had B&L, Bushnell 3200, Simmons ATV 4.5-14, Leupold VXII, Nikon Monarch 3-10x, Weaver K2.5 & T-36 (2), and others. Tasco 8.5-32x
So far the clearest and best has been the Leupold. Unlike the Nikon Monarch, the image is full to the edges. Comparing them very closely, the Leupold image is a bit sharper.
The Bushnell had terrible edge distortion. Moving the scope horizontally in the woods made all the trees at the edges bend, giving me a queasy feeling.
The Simmons scopes have a clear and very bright image, but I've had to return one because the adjustments wouldn't hold zero after a couple of years of intensive 10-22 shooting. The 4.5-14 ATV is no longer available. Too bad, I loved that scope and have them on several rifles.
The Tasco 8.5-32x (japan) is a great scope; not as bright or clear as the Simmons, but very accurate. It doesn't focus to 50 feet...bummer!
My B&L scopes are great, but after about 50 years, one eyepiece couple has apparently delaminated.
