Arch isnt that hard to use, just more maintenance, you have to update often and you can break things easier. It is defiantly harder to install. Thats why I recommend Garuda as it has a nice gui installer. It comes fully riced too. KDE dragonized is what i went with. The non gaming edition.

You will have to maintain your new system with fresh updates very regularly. You will have to get used to going through .pacnew files. Luckily there are easy ways to do this using meld to view pacnew files side by side with their corresponding config file that helps you migrate data easily.

Being an arch based distro your on the bleeding edge of linux and this means sometimes you will get cut! But an update will come along fairly quickly to heal those wounds. For instance the screen rotation broke a few months back. Easy fix in udev config though.

Debian based distros are pretty bullet proof, takes a but more to fuck one up. You'll have to wait a lot longer for the things arch users get every day.

Personally i don't find garuda to be that hard to maintain but Im used to arch already so I know what to expect and more of how to fix things. One of the best things about garuda is it uses brtfs by default and sets up snapper for you so when things go wrong you have an easier time fixing things.

You can always try it out and if it's not for you you can move on to the next distro. And hop until you find what your looking for.

Best of luck!
