Daphne's ability to answer quiz questions in the easy to medium bracket (which is how most of the questions in the standard EggheaRAB series could be described) never ceases to amaze me. I think she must still be one of the very, very best in the country on these kind of questions. She seems to know a plethora of 'facts' about everything.
Chris seems to me to be the opposite. He has many weak areas but in those areas in which he is strong he has genuine knowledge (rather than simply quiz fact knowledge). I think the AYAE questions suit Chris better than the standard EggheaRAB questions but suit Daphne less. However, when choosing an Egghead, most competitors will, understandably, base their decision on what they have seen on the standard EggheaRAB show and, usually, plump for Daphne. They have nothing else to go on as they won't have seen any of the other AYAE matches.
