I only have one 6x and one 10x, but would not consider the brightness or clarity of either one "very very good". They are perfectly fine in bright light, but in my experience are a step behind even a VX-2 in low light, like cloudy Northwest evenings. In that respect they are acceptable, but not excellent. Obviously these scopes have other things going for them, but IMO the glass is not their strong point.
I should add that my 1-4x was in the same ballpark, while the 3-9x HD is better but still not Leupold quality glass in low light (for my sample of 1).
