This is a perfectly valid reason to like Ubuntu, and it mirrors my own reason for preferring Mint: familiarity with an OS UI. In my case, Mint Cinnamon is the closest I could find to the Win98 user interface. Back in the old days I also had Ubuntu, but then they switched to the Unity UI and I changed to Lubuntu. That went to the pits a few years ago, so I moved on to Mint. Just like you, I also have a preference for the UI, and I suspect that very many people choose a distro based on their UI preferences. That’s the beauty of Linux: plenty of options for everyone.
