One thing I’ll say is that for a lot of distros these days you shouldn’t really need to use the terminal much if ever. That being said don’t be scared of the terminal. It’s just another way to tell the computer what to do. It takes some learning but if you want to learn things with the terminal you might eventually find it easier/faster than using the mouse for some things. Go through some tutorials and you’ll probably find out that the terminal is not that actually all that scary.

Most distros allow you to try them out before you install them. You can run them from a USB stick to let you try a few out before you settle on one. You won’t be able to install any programs this way but you’ll at least be able to get an idea of the interface and see if there are any you like more than others. Even still you can dual boot your PC with Windows + Linux and switch back and forth whenever you need. It’s not an all or nothing ordeal. I still have windows 10 on my machine but I rarely use it now.

Gaming on Linux is better than it’s ever been thanks to Steam coming with proton out of the box. protondb.com is your friend for figuring out what games you can run. That being said there are occasionally some rough edges that I have run into personally. I can run most games I want just fine but occasionally I have some issues. I’m just telling you this so you know it’s not like a flawless experience. Then again I’ve also spent plenty of time trying to get games running on my windows PC in the past too so…

My recommendation for a first Linux OS is Ubuntu because in general it’s the most popular and has the most support.

Best of luck!

I’m a fan of Voyager. Very nice experience in my opinion
