Of course it’s a good thing, but it’s not something Gentoo is particuarly goot at it (nor any distro, that is) but its detractors claim Gentoo says is “lean on resources” only to “debunk” that.
And the myth that is “supercomplicated”, but in the end the only “difficult” part is to install it - in the daily, pedestrian usage it’s pretty much like any other (rolling release) distro. Well, of course except package installation/update times, but it’s beyond to me why people created that false urgency of needing to have everything installed and updated the second you issued the command. It’s not like you won’t be able to use your computer at all while Portage does its thing.
