I don’t understand the hate. I have been using Manjaro as my sole OS on two machines (a Thinkpad with XFCE, a Surface with Gnome) for several years, and have never had any major problem. Everything just works. The same could be said of Mint (which I used to be on before Manjaro), but I enjoy having faster updates on Manjaro. So I guess, from experience, I am very happy with it.
