I only have one scope with side focus and a couple with front objective parallax adjustment. I agree with both of you. I know the side focus is touchier on various distances but easier to adjust, especially for a RH shooter. For us southpaws its a bit trickier. Most of my rifles have a scopes of 2-7 or 3-9 magnification which suits me fine for 99.99% of my hunting in the woods of PA. I'm sure the same can be said for most gun owners.
But mrbb has a point on the fact that a lot of guys like the "tacticool" look whether they use or need it or not.
