Have met William a few times and it was both good (quite charming at times, quite warm at times) and not so good (a bit like what Sitting guessed). He was best at the sports related events.
He definitely didn't seem to be listening to others at times - he would ask questions, not really listen to the response and would seem to be waiting to make his reply - usually a joke that would fall flat (have seen this in a few videos too). However, these were only small snapshots and I have seen in some videos where he has come across well (and quite funny at times too).
Edward was super nice.
I have acquaintances who have met P. Anne (really rude apparently), Sophie (heard good and bad things), Fergie (friendly and jolly) and Andrew (no one had anything nice to say).
