I have been using Debian Testing for six years now, and I have no complaints.

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.

Ubuntu also for sever and I like to mess around with Kali for fun
