Hard to choose between Wembley and Boober. Wembley was my favorite growing up, but Boober has gotta be the funniest of the Fraggle five, with his deadpan humor and big vocabulary, which IMO elevate FR to that additional level where it can be appreciated by adults. But I love Wembley to death, he's so innocent and genial and just wants to be accepted- easy to identify with. Call it a tie.
