By many things and in many ways 
Colored icons.
More than as double as much icons than Blender.
A user configurable toolbar at the top.
Reorganized menus.
Cleaned up menus without this much double entries.
Extended User Interface. Even with Blender 2.80 you have hotkey only tools.
Our own keymap. Not a half baked hybrid between all the other apps out there.
A better readable standard theme.
Left aligned text!
Some neat new addons to improve usability, like the reset 3D View addon.
And much more.
But the code is just half of the show. The Blender manual for example is basically unsearchable, has a odd structure, and is more or less useless for users. We work at a completely new manual, rewritten from scratch.
