In my case, it's a "misconception" based on being the guy who has to orchestrate a production pipeline from start to finish and pay the bills for everyone along the way.

Blender's UI may be many things, but like any tool in this field, simple is hardly one of them. In any case, a significant problem in practice is that Blender's natural ways of working don't always match what is used by just about everyone else. Sometimes it's got just the right feature to model something in a certain way, but you then incur a disproportionate cost to adjust that asset so it's useful as part of your overall pipeline, and while the UI for the handy feature might be decent, the overall process is glitchy and error-prone.
