The [VirtualBox manual](https://www.virtualbox.org/manual/ch04.html#idm2099) states:

> 
> [..] some Linux distributions already come with all or part of the VirtualBox Guest Additions. You may choose to keep the distribution's version of the Guest Additions but these are often not up to date and limited in functionality, so we recommend replacing them with the Guest Additions that come with VirtualBox.

Right now, the latest guest extensions on the [VirtualBox Web page](https://www.virtualbox.org/wiki/Downloads) are version 5.2.10, while the [`virtualbox-guest-x11` package](https://packages.ubuntu.com/bionic/virtualbox-guest-x11) is version 5.2.10 as well. It seems to me that using the package instead of downloading the ISO from the official Web page would have the advantage of automatic updates at no obvious disadvantage. Am I missing something here or is the recommendation from the manual just outdated and/or not applicable to recent Ubuntu versions?
