Manjaro is the Linux Mint of Arch linux (non derogatory). its stable but let's you enjoy the benefits of arch but you you're tired after work and don't want to have to tweak your bspwm dotfiles for the thousandth time because a program doesn't respect your rules
I've done my years of carefully tweaked TWMs and manually installed Arch but seriously after 8-9 hours of dealing with computers, you dont want to have to deal with random stupid issues and Manjaro is perfect for that
