I've held most of these in my hands and typed in apps. They are not even from the same universe as the Macbook 12".
Razor? Dell? Not even close when they are in the hand.

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...
