This is very very subjective. All the tricks are very visual and require practice to pull off perfectly. I have gotten the best reactions out of panic. The advantage with panic is that the audience goes hands on only at the end of the trick, which is exactly when you want them to go hands on. the other two tricks are transpositions of sorts with visual aspects to both of them. The only problem is that every time I have performed them somebody always says "can I look at it" meaning the card/coin to be transposed. Regardless that is something I will perfect with presentation, but more importantly I would see the preview and think about what are the types of effects I do. Digital Dissolve may be awesome, but if you only do that one coin trick, imho it begs to question. If you do some coins, that is awesome. If you do mostly cards look at the other two and decide what you want to do.
