RedHat here in the late 90s, back when you could still find yourself writing a “modeline.”
Then Debian in the early 00s when apt was still a major discriminator. Finally, Ubuntu around 2008 just so I was running the same thing I was recommending to family members for ease of use. (At the time, Ubuntu sported the same ease of installation and hardware detection I’d found with Knoppix.)
Now on Xubuntu, but seriously eyeing a return to Debian.
