Personally I prefer the Cardini change.
They're practically the same thing, but the Ego Change is basically a slower, quieter version of the Cardini.
If you want a card to change in a snap, visually, use the Cardini. If you want a change that happens almost undetected, like, under your waving hand, then the Ego Change is for you.
Daniel Garcia's version is a bit quieter, I must add.
