I like the ease of install and rational defaults the OS chooses for you. It's a breeze compared to installing Arch. It's a great way to get started with the Arch side of linux. Let me test pacman and rolling releases without the time involved with getting used to arch and doing everything from scratch.

I've tried Linux Mint and other options such as Arch but I like that Manjaro is more lightweight in comparison as it runs steam games faster so that I can also stream with better quality too
