Up until recently, Elementary OS was my platform of choice. It's an elegant, simple, and user-friendly solution for the desktop. One thing that the Elementary developers do that I believe is fairly wise is to not allow upgrades from one major release to another. In other words, if you use Elementary OS Loki, you can't upgrade to Juno. To get the benefits of Juno, you must do a full-blown re-install of the OS.
