The first one was pretty cool. I didn't enjoy the second one as much, mainly because I can't stand Richard Dawkins. He's got this sort of self-superiority that probably comes more from his accent and intellectual mannerisms than anything else. It's probably hard to be a distinguished British guy because everybody assumes you're aloof (although I'm sure there are plenty of anglophiles that find him more approachable because of it).
I liked the second vid less, too. I doubt it's a British thing (you don't find Attenborough smug, do you?) but he never comes across as smug to me; just very straightforward.
