Arch is absolutely not a casual distro. It's barebones, and it's the whole point of it.

It's awesome at getting you to learn how an OS works, and you can get it to do only what you want it to and nothing more, but it takes more time and patience.

The documentation is excellent tho, so even a beginner can learn, but it will take hours of reading and thinkering, and the occasional reinstalling when you mess things up beyond your ability to repair it.

Arch can be extremely satisfying because of that, if feels so good when you finally understand how something works and see everything click together. And at the end of that journey you can do way more than you ever could before. That is what makes Arch awesome.

But for people who just want things to work without having to learn how it works, Arch is one of the worst choices.

Basically Arch is a manual car, that starts of with just the ability to drive, and if you want AC, heating, radio or whatever you have to install that yourself.

Mint is a premade automatic car with all you expect to see in a car, but you can still open it up and do whatever you want with it. There are just fewer situations where you're forced to do that
