Well, I was comparing it to the MBP and this is an area of personal preference but I like/dislike various things about each.

Razer and Dell were very comparable to an MBP 13 for me. I would be happy to break down some comparisons for you (according to my personal experience/preference having owned all 3) but I would definitely agree the System76 is in a different build quality category...although (IMO) it makes up for it with its first-class hardware support.

Haven't owned or even used an MB 12", but I am surprised you like it so much, most things I read about it complain about the keyboard: https://www.reddit.com/r/MechanicalKeyboards/comments/2yhemp...

Keyboard is also one of the most important things in a laptop for me personally...
