I have Linux Mint installed on most of my machines in the command center as the primary boot option or available in a dual-boot setup. It is my favorite right now because most of the tutorials have been based on Ubuntu or Debian (Mint is a fork off them), it is so easy to set up and install in a very short period, and it seems to be very stable for some of my higher end hardware. I won’t list all of my hardware, but it runs very well on my Dell XPS 9550, a HP Z600 workstation, and my custom-built, HAL, which is pushing to two 4k 28″ monitors. HAL is having issues with some of the Windows 10 updates, so I run Mint exclusively on it now.
I also use a few security distributions like Kali, Slingshot, and Parrot.
