I like both versions, but I think this one is better. I think it's better to have your friend on his own when he asks if you're cheating, so that it makes it look like the camera is from your point of view. In the other version you had him appear behind you, which was a cool effect but looked a little strange because you weren't facing him when he was talking to you.

On the whole, it's a great video. I like the comparison of reactions. Good work!
