Garuda is the OS I've been using as my main since 2021 when I switched from Ubuntu. While I love it, and Garuda is aimed at making Arch easier to use, it is still Arch. I would say if this is your first time installing Linux, Garuda probably isn't the best choice, rather it's something to move up to when you're more familiar with the OS. For a first time user I'd suggest Ubuntu, It's not the flashiest, and some people will doubtless deride it for this or that, but when it comes to being user friendly it's pretty hard to beat. Then once you feel confident with that, aim for something more advanced like Garuda if you still want to do so. Good luck in moving over to Linux!
