On one hand, I still hate the MS Office "ribbon" UI to this day and much prefer the denser and more compact Google Docs or even Open Office layout.
On the other hand, Sketchup was hugely popular and very easy to use compared to its peers when it was released, and quickly became the de facto tool for simple free basic 3d modeling, in no small part because of easy and clean it was, I think. But they got bought out and then abandoned, I think? It doesn't have anywhere near the power of the other software anyway.
IDEs are another example. VScode seems a lot cleaner and leaner than old IDEs, and Jetbrains ended up copying them too (a controversial change, of course).
Photoshop is the one that always gets me. Twenty years of using it and I still can't get used to its layout. It's just so many different weird widget types mashed together in a way you don't see in any other software. I much prefer a docked toolbar like in Figma or Paint Shop Pro. I hate that I use it... I feel like a hostage every time I open it.
