With 3Ds Max listed as good UI we really must just have different tastes, hah! :D
You've given quite a list of tools with different purpose.
For 3D work I would personally rate
Modo 3D, Zbrush > Blender, Houdini > Softimage XSI > Maya > space intentionally left empty :P > 3Ds max
Blender UI looks very nice and is very customizable. I think it's "ok" in beginner discoverability (none of 3D softs is great at that really) but when you get experienced with it it's one of the best.
I really like how they managed to keep all the tools and views pretty consistent given how many things you can do in it. Whether you are working on objects, vertices, nodes, movie clips you get the same shortcuts where possible.
Fascinating, I would have ranked Softimage XSI above blender (even modern blender), it was just that intuitive to me.
3Ds max being dead last is fitting, people who think it's peak UI just have stockholm syndrome in my opinion.
