Best way to display number of selected objects in a Status Bar?

I am thinking ways to display number of selected objects on my application Status Bar.
The application is basically a gird view of objects and I intend to show the number of objects listed as well as the number of objects selected by the User.

I browsed through multiple apps and found various implementations e.g.
Windows Explorer - (100 items, 2 selected)
Gmail - 2 of 100
Powerpoint - Slide 1 of 10
MacOS Finder - 2 of 100 selected
Ubuntu - 100 items

I couldn't clearly derive a best approach. Some applications are using Items and Selected keys, some show just the numbers.

What do you guys think. From a user's point of view, what is more relatable?
