One thing that's killer for me in MacOS vs Windows, regarding consistency, is text fields. They always behave the same (except, of course, for weird apps, say ms office). CMD+Backspace will delete a whole word even in password fields or system settings, etc. This is always hit or miss in Windows. I know it doesn't work for passwords. In Windows explorer it works... sometimes. It works in the address bar, but not in the preferences or when renaming a file.
