I only see one visual anchor in the old one, the horizontal rule at the bottom separating Menu Bar. Everything else is just jumbled together.
The new one at least attempts visual anchors with gradient background boxes and by right-justifying all the controls.
I grant you the contrast ratio is worse and Apple should read Contrast Rebellion. And I personally don't care whether they use a checkbox or a switch, as long as its placement is convenient and aesthetic. I use Linux with Gnome 4 on my workstations, which uses switches for settings, and a MacBook laptop with checkboxes, and iPad with switches, and none of that makes any difference to me.
But otherwise I prefer the layout arrangement of the new one. Vertical and horizontal spacing are more orderly, left-justification of text and right-justification of controls improves UI consistency, and grouping within gradient boxes is more aesthetically calmer to my eye. Just my $0.02, to each their own.
