I recently finished the first model for my new TK army, and in my own humble opinion, it is one of the finest models GW has made. Firstly, its size. Its huge! both taller and longer than a Land Raider, and it dwarfs almost anything on the battlefield (except the O+G Aracnarok spider). Secondly, the detail. You can do justice to this model simply by blocking colours and using washes to bring out detail, but if one were to go to town (as I tried to) you can make it truly special.
