Not versions. Distributions. They’re all developed and maintained by different organizations and are geared towards different types of users. It isn’t like Windows where your choice is Microsoft or nothing.

This means that different distributions can have a completely different UI and even approach things like installing software in very different ways. That’s why I tell people that if they install it and they don’t like it, try a different distribution. Or a different version of the same distribution. Changing your desktop environment can make a huge difference. Most distros push GNOME on their flagship version, but I’ve had a much better experience with KDE. If you don’t like the GNOME version, download and install the KDE version. If you like a Windows-style desktop, you can have that. If you prefer Mac, you can have that. Or you can do something completely different! The sky’s the limit, really.
