Blender UI is great, but Cinema4D UI is arguably better. I've used both for 10 years.
I think most engineers and designers forget that they're just tools. Vim or emacs? PyCharm. Whatever works for you. Stop letting tools define your craftsmanship. This comment reminds me of pixel peeping that most enthusiast photographers do...comparing MTF curves for days. How about going out and taking pictures, learning composition and narrative, story telling and photographic experimentation? But they're too enslaved to their tools.
I guess that too can be a hobby?
