I think intuitiveness and density are orthogonal properties (although often both desirable).

Regarding Blender specifically:

Do you have a background in 3D modeling?

I am genuinely curious.

I don't come from an digital art background and I bounced off Blenders UI several times but after doing a tutorial or two now I find I can use it for simple things. I have always wondered how much it was 3D modeling in general vs. Blender specifically.

In a similar case I have used both Inkscape and Illustrator as an amateur and, much as I love open source, there is no comparison. Illustrator was significantly easier to use and worked better.
