In my opinion, I like Tony Slydini more because he is more as an underground man who work for his dream, and he request nothing in return. Unlike Dai Vernon, I think he is a bit of show off, and attention grabber. Another thing I like about Slydini is that he is the master of timing. When you watch him do magic, his timing is so good that you can barely read his movement. Moreover, over the years, Slydini creates so many good performer over the world. They are all successful in his magic, too.. Last but not least, Slydini is the only one who can still fool Dai Vernon. In short, I will go for Slydini over Dai Vernon.
