Taker's just the best. He's adapted to the times so well and has never gotten stale in 20 years at the main event level in the same company. Easily the smartest wrestler ever. Always changing something, whether it was the color of his attire, his facial hair, his ring jacket, his hair, his moveset, his theme music, etc.
The question though is pretty much, "Do you enjoy Taker more when he was more character oriented, or ring work oriented?"
I'm gonna have to go with the 2nd half of his career though. His "legendary status" in the 2nd half has led to some amazing matches and feuds
