From the UX point of view I very much prefer the oldschool way of „ticked“/„nonticked“ instead of „left/right“ switch.

To me, they have slightly different semantics: I perceive the checkbox as “passive” form element (i.e., only to have an effect on form submission), whereas the toggle switch I understand as instant action (i.e., effectuated immediately, on click). Unfortunately, it’s not consistently used that way in practice, which makes the situation confusing at times.

I wonder how much the culture you're used to matters for this. What if you grew up with right to left writing system. Should your switches have the off state on the right?

Britain has their light switches operate the opposite way around to the USA.
