the one by Sideshow looks more realistic and movie accurate,he's more slimy .The one by Attakus looks like the digitalized version of the character.he looks almost cartoonish..And I have seen him many times in person..Its really a nice and imposing statue, but The one by Sideshow is just more realistic.Even the old maquette by illusive looks more real than the attakus one.IMHO.
