System 76 customer here. I just replaced my 2011 system 76 lemur with a new lemur. I have Ubuntu installed on both and have never tried pop os. I was very happy with that laptop and the company in general. It actually still runs okay. I did replace the battery after about 5 or 6 years. I’m thinking of trying out nixos on it.
My guilty reason for upgrading was I wanted to play dwarf fortress at more than 5 fps…
