Alpine Linux, because it uses OpenRC and musl, it’s an interesting choice a little bit different but I really like it nyself for servers.
Gentoo, the biggest source based distro, has Emerge, a very configurable package manager.
NixOS, uses the Nix programming language to install packages and configuring the system. Very powerful and breaks many conventions about Linux systems
VLC ships their own codecs which is great on Windows, but a bit suboptimal on a typical Linux desktop installation since you’re probably going to have GStreamer or ffmpeg available too for the rest of the software like video editors, web browsers, etc
