Korriban's tribute to Ancient Egypt and the drawings in Gnost's timeline and different drawings from Tales of the Jedi strike me as better than th CGi crap from TCWs version. The EU rightfully painted Korriban as a holy site revered, harboring a dark past, as well as made it a place of great foreboding and power. Then Tombs of the Dark lords, and the way it's described and shown from the Bane trilogy and Tales of the Jedi are all better portrayals
So Korriban wins
