Consistent but optional, sounds inconsistent to me. Anyways that was 1 example, here's some more.

⌘R Reload in Safari; reply in Mail; reveal an alias's original in Finder

⌘L Address bar in browsers; message filter in Mail; clear to previous mark in Terminal.

⌘I File info in Finder; italics in text; inspector in Terminal.

I can keep going. This is not to say windows/osx is worse or better, just that claims of consistency are not suitable on either
