Pop!_OS.
I have tried many Linux distros since I finally abandoned Windows for good, but in spite of the fact that I prefer Fedora over the other kernels, Pop!_OS as a distro, along with Pop Shell, is just everything I've ever wanted in an OS and all else just feels inferior.
I'm a dev, though, so it would make sense that an OS made by devs for devs would be my cuppa.
Most users won't need 90% of what I, specifically, love about the OS, but it's also the first distro I've found where everything I want to use just works out of the box without spending hours troubleshooting, and that's not nothing.
