Alright.

So in nutshell Blender has bad UI because it is splitscreened and has horrible GUI.

Then take some time and make it like in Max, XSI or anything. They have split screens too, at least when I tested Max '09 it had split 4 screens.

The confusion in the GUI comes from the lack of experience. If all of the GUI's would be that customizable, people would be horrified of the basic Windowsian blocky toolmenubars.

Myself? I love it. I can have all the windows I want and need in order and placement I need. There is absolutely zero "cluttering" or being bad. The anti-blenderians are just inexperienced of the GUI-system. At least I haven't seen senior Blender user with having sad face everytime they launch it.
