I enjoyed Shawn's trick. Very clever and I wasn't at all surprised it fooled Penn and Teller.
Etienne didn't really do it for me, if I am honest. It all seemed a bit too quick (possibly the editing, but I suspect not) and a bit, well, "bitty". As with Mathieu Bich, there was something very obvious that didn't seem to fall under suspicion at all. I am sure that, if Iain watched it, he would have thought the same as me.
Presentation-wise, I really liked "Manuel", the Cuban from Mexico.

I liked his patter and found him the most engaging performer in that show. Shame his trick got completely revealed. I cannot say that I was remotely bothered that it relied on gimmicks.
While I knew what was coming with Chris, I enjoyed the fact that he'd done something very different, and had tried to put a new spin on fooling P&T and was using the surroundings to his advantage. It didn't entirely work, but it was good to see something new.
