There are many linux distros like Ubuntu, Mint, Debian, Arch, Fedora etc, etc. and they usually come with a Default Desktop Environment Cinnamon, KDE, GNOME, XFCE, etc. etc. This is generally how the UI looks and functions. Menus, Window styles, buttons, and general overall visual theming. There are many ways to make the linux desktop environment better looking and functioning than macOS. Mac doesnt even have the ability to auto snap and resize the window to the edge of the screen until recently. And even then it decent at best. So beyond being able to fully customize the look of the desktop environment by using different ones with themes options, you can choose a DE that has better customization for user interaction that suites YOUR needs. Ofc Apple has a whole ecosystem of products that and a cloud that syncs your stuff across, but that comes at the cost of near zero customization ability…But whatever floats your boat. check out unixporn community, there are some really nice setups over there to give an idea of what is possible.
