If you are scoping a light weight rifle, it'll probably feel top-heavy to some with either scope.
The weight difference is about 5 oz between the two scopes, and the 3-9 is not much smaller in bulk than the 3-15.
As far as glass in HD or not on these, between mine, I've reached the age where the difference is somewhat mute.
You'll have to decide if you're shooting far enough to need the extra magnification, but for hunting, you're probably not.
I like the SWFA scopes, in fixed and variable, and wouldn't hesitate to use either one.
