If I remember correctly, POP started out as being intended to be used mostly in Education, System76 has been around forever and at some point made it their default (and I think they sponsor the project as well).
I just use Mint even on my new desktop. It still works well on my old stuff. I have a really old Dell XPS laptop (i5) and it does what I need. If I felt like I needed it to work a bit better/faster I would have the WM changed over to either XFCE or LXDE like I mentioned above.
