My favorite Linux distribution is Ubuntu.
I have been using Debian Testing for six years now, and I have no complaints.
I don’t like Linux distributions in general and for the specific reasons. So, there is no my favorite. But I prefer common wide accepted original distributions and not slightly customized derivatives.
Ubuntu also for sever and I like to mess around with Kali for fun
do you like haching on Kali well washy and george are around?
They help me with it! But only pen testing
Ubuntu and debian based distros have been a long time favorite. Recently switched to Fedora and the Cinnamon desktop. It has a nice feel and user experience as well.
What is difficult now is the base OS to choose, but also the desktop experience. I think the desktop choice is also what makes the Linux experience and distro choice for people these days.
