I used Manjaro for years and decided to try something new. I like the idea of being able to say that my computer works exactly how I want it to, no less no more. But the truth I'm not smart enough and it ends up kind of half baked. It's still a lot of fun, though.

I also tried Arch two years ago. Its installer was familiar to me because when I started using Linux (2007) most Linux distributions had such an installer. But I'm too old to mess with Arch, so I prefer Manjaro.
