From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Something a Gentoo user might care about is the distro's compile time options. Ubuntu uses -O2 and LTO, Debian uses -O1. Debian has always been noticably slower overall for me.
Don't do what I did and go with Tumbleweed. It gets more updates than Arch.
It's not that difficult to build your own kernel based on the official debian one: https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-common-official
It doesn't make much of a difference in the kernel, but I definitely notice it on Debian's Firefox vs Flatpak.
