Chris Packham Vs Simon King

I have option of interviewing either Chris Packham or Simon King for a piece I'm doing. Since, as you may have noticed, I make fairly free with my fancies, I'm rather partial to both. Chris has the benefit of being a childhood hero of mine, while Simon's continued hair loss has only made him more appealing to me - it's probably in part due to that fabulous animal-watching whisper he does.

Which one would you pick?
