Debian Stable is my distro of choice these days, mainly because it respects my time by avoiding frivolous changes, without getting in my way when I want to change specific things.

Setting it up for modern gaming hardware required a couple of extra steps, which I found to be worthwhile. I now have a system that has proved dependable whenever I need to get work done immediately, and very capable whenever I just want to have fun. (The Backports repository makes bridging that gap easy in most cases.)

Linux Mint is what I suggest to new users. It's based on the widely supported Ubuntu distro, has a good sized community, and seems aimed at people who don't already know unix. It also makes a point of stripping out problematic Ubuntu-isms, and has a Debian-based edition waiting in the wings in case that ever becomes unmanageable.

My desktop environment is KDE Plasma, which you can install on just about any distro even if it's not the default. It has a wealth of useful features, lets me tweak or disable them as I see fit, and avoids trying to turn my desktop into a mobile phone interface. (I used Xfce in the past, but its adoption of Gtk 3 transformed it into something that I found frustrating.)
