I've now tried both and have to say that they are both easy to use. Still I like Presefy (http://presefy.com) more because it's so easy for anyone to remotely view the presentation from my unique presentation url and not a randomly generated url.

Nice thinking with the QR-code pairing, it's really easy to get started with.

I will give it a spin and see how it differs from http://presefy.com - which I'm currently using.
