Someone will perhaps confirm or deny these differences: There is no such thing like shared memory in Windows (disadvantage). The lack of OS buffering in Windows turns out to be a "built-in" advantage when running Oracle. In most cases, one would rather mount file systems with the directio option to avoid double buffering. Windows does not need to disable what it does not have.

Whenever I ran Oracle on Windows and Linux, these were different machines, so I can't really compare. But I have only seen Oracle getting unrestartable only in Windows, and exactly only once.
