Earlier quoted context omitted.
Anecdote: Most of the software I use isn't available in `apt`, or the version there is dated. I prefer to get software from its official source, not a third party I don't know will have the current or any versions. And, there is more to software than free/OSS.
I switched to an Arch based distribution and it's night and day. Almost everything is available through the AUR, you even have the choice to rebuild a package or to use a pre-compiled one. I'll never go back to Ubuntu and apt. Oh, and it's a rolling release so my install doesn't break every 2 years with the new LTS upgrade.
Meanwhile, on Ubuntu/Debian-based systems I can just install locally or use a third party repository for the things that need to be more up to date.
