There are occasionally little things that are available on one distribution and not available on others. For example, with Cinnamon and Linux Mint, you can right click on items in the start menu and there will be an option listed to uninstall the clicked program. This was (and probably still is) missing from Cinnamon in Debian / Fedora.

I imagine there are other things like this with most distributions.

Or for something like Plasma, you can go with Kubuntu or KDE Neon. Both of them are Ubuntu derivatives which are meant to be used with Plasma. But KDE Neon will get you the latest Plasma version, and Kubuntu will not be bleeding edge.

I like to get a comfy "out of the box" experience, which can differ quite a bit between distros, especially how smoothly it all fits together.
