I’ve always used Windows and am super comfortable with it. I have set up a dual boot with fedora but don’t use it because I have never identified a need to use it. I see a lot of windows hate, so what does Linux have that I need? What can motivate me to migrate? What is a good Linux to have for a desktop + steam?
Personally I would say start with Fedora and try Gnome (maybe with some extensions like dash to panel) or KDE. KDE is more buggy poorly, but has far more features. On Gnome you can run some KDE apps too though, Dolphin for example is awesome
In Fedora add Flathub and try to only use Flatpak apps from there.
Then if you think you are happy, you can try an immutable Distro. They will basically never break, but some advanced apps and plugins may not work that well. In theory you can simply install these apps as RPM apps though too.
Fedora Silverblue/Kinoite with Flatpaks is SO ahead of Windows. Updates go in background while running, and after a reboot you always have a completely new system. Updates are fast, and extremely stable, due to the system image being like on Android.
Flatpaks run in containers, isolated from the system. They are getting better slowly, but are mostly not made to run there, unlike apps on Android. So they cant be as secure, but still are waaaay better isolated from the system, you can restrict internet access, state the folders they are allowed to access and way more. On KDE in the settings, in Gnome using Flatseal.
This is also wayyy more modern.
Also, Dolphin, or actually any other file manager. Dolphin runs on Gnome too perfectly. They are soooo much better than the Windows explorer crap. Extensions everywhere. Tabs. Drag-drop menu. Creating links. Windows is so horrible to use.
Also Linux is way better at processing small files. Try starting GIMP, unlocking a big Cryptomator vault (for cloud backups). Windows just crashes sometimes.
Also, Linux has so much more Opensource software for nieche purposes. Windows has a lot, and a lot of old crap like Openoffice, FreeMind and other not maintained software. May not be there on Linux, because its outdated. But just look through flathub.org, its amazing.
