In terms of saving space, I like the shoulder tilt, but I wish the head was rotatable like Fett so you could choose which way to face him. I like Maul being straight so I can angle him however works best for the display, ones like Palpatine sort of predetermine what you do with them because they're fixed looking one way. I especially think this because Vader and Palps are the same pose, but it would have been cool to form a V out of the two busts sort of being back to back, but can't do that.
