What's the difference between the two? Is one harder than the other? Is one of them more convincing? Is one more angle sensitive? What other differences are there? Trying to find out which one might be more appropriate for me before I spend money on one.

Some Ad copy:
"The 'Truffle Shuffle 2.0 is Karl Hein's development of Derek Delgaudio's sensational Truffle Shuffle.

This is, in our opinion, the best in-the-hands false riffle shuffle in existence. While it might look like a normal shuffle, it is in fact completely false. It does not disturb the order of the cards at all.

So, what makes this version better than other in-the-hands false shuffles? In short, all of the small subtleties. Karl has devised a method which makes it look like one half the deck is being legitimately shuffled into the other. In fact, the clever workings mean that the two halves always stay separate. This is a reliable, deceptive and convincing false shuffle that you will e able to incorporate into any of your card routines."

I practice both. I recommend to start with the Truffle Shuffle from Delgaudio, which is easier to start with and can be rapidly
used efficiently. I find Karl Hein version ( Truffle Shuffle 2.0 ) more deceptive in the sense that the bridge is done palm down
with the deck towards the ground, just like a normal riffle shuffle, unlike the Truffle Shuffle whose grip is with your palms/wrists up.
But 2.0 is also more difficult to master, in particular
to get the nice looking bridge Karl Hein manages to produce. But both are somehow not that far from each other, so if you master the Truffle Shuffle you can get a try to 2.0 version.
