Everyone has different opinions. In the end the different versions, or distributions, are basically the same.

It starts with the Linux vernal, that as far as I know, handles communication with the hardware, and things like directories, storage, users, permissions. On top of that, every distribution creator puts a destropenvioment, like gnome or KDE (plasma?). Gnome is kinda like Mac is, KDE can be what ever you want, very customizable.

Than there is the package manager. Fedora for example uses yum or dnf (dnf is the new version I think) and Ubuntu uses apt. The package manager is like your app store, that you access over the command line. It is managed by the owners and ist mostly safe to download anything. (Installing Spotify would by ‘sudo apt/dnf install spotify’. So pretty easy to use.

On top of that the distribution has preinstalled programs, like the browser, writing tools, and some useful apps

That is basically the only difference between distros. You can even get different spins of a distro. If you like fedora, get it with the KDE desktro envioment. It’s all the same basically.

So put something on a usb drive and boot from that, try it out for a few minutes and than look at others. There are also websites that allow you to boot into different distros.

If you like something, just install it, maybe as a Dualboot first next to windows (best is on a different drive) and just try it out. If you don’t like it, just jump to another one.

Linux can be a little bit pain sometimes, but in my opinion it’s worth to invest the time. Have fun!
