I agree, I discovered Ubuntu around 2003/2004 when they were giving out free CDs to anyone that requested them. Once I discovered that Ubuntu was based on Debian, I started using Debian and wouldn't look back. Even if you need something that only Ubuntu provides, you can get the .deb package for it and install it yourself. I prefer relying on Debian stable if I need to maintain anything for more than a year or two (and am realistic that software usually fails fast, or hangs around for a long time). It's possible that my knowledge is dated at this point, but I always preferred working with the Debian filesystem and tools more than Red Hat/Fedora's filesystem and tools (rpm and yum). Apt and apt-get somehow "clicked" with me more than Red Hat's tools, and I even took multiple classes on Red Hat administration and general usage (although do far less administration in comparison to software development than I used to do in the early 2000's to mid-2010's).
