I recommend Manjaro with the default desktop environment XFCE. It's a rolling release, so you always get up-to-date software. Installing software is easier than any other OS (just use the Add/Remove app not the command line). I have tried desktop Linux for years and I never really got an effortlessly stable and worry free system until I used that distro. I've been running it on one laptop and two desktop workstations now for over two years. It never interrupts me, I update when I want to and it's based on Arch so it's got excellent documentation.
