As a daily driver distro
Using it as a standard desktop distribution for average users.
All of the distributions we’ve looked at can be turned into typical desktop Linux systems by adding an unprivileged user, a desktop environment and some desktop apps.
When evaluating Gentoo as a daily driver distribution, the first problem is that it takes quite a lot of expertise and work to get it into that state. Portage is a highly robust and reliable package manager, but as it’s source-based, adding a new package can take a long time. Gentoo deliberately omits some automatic systems, another barrier to making quick, easy changes.
