You should've probably proven that the Sanctuary Guardian is Seath's creation before claiming it to be his best.

There are some points disproving that theory. 1. Seath likely attacked Oolacile himself. This is hinted by the Crystal Golems, along with the Moonlight Butterfly found in the area. Both of these creatures are specified as being his creations, and one of them holds the princess of Oolacile captive. 2. The Sanctuary Guardian is just there. It's never explained why it guards the Sanctuary, only that it does. 3. The description of its soul says that it appears closely related to demons. Seath didn't create the demons, the Witch of Izalith did, indirectly. 4. Neither Tark, nor Najka are confirmed to have been created by Seath. Actually, none of the creatures you mentioned are even remotely related to him.
