Well, Wood has got a "nice" face (damning with faint praise), and there is a vague resemblance, but let's look closely at each distinct facial feature: Bono's face is markedly stronger in every sense: the eyes are enormously more intense, the nose is more pronounced and full of character, the mouth is wider and way more sensual, the chin is more dramatic and masculine. But even more importantly is the overall emotional impact of each respective face. Wood projects a mood of vaguely troubled weepiness; Bono projects a mood that is intense, confused, committed, wise, yet naive at the same time (my god, those eyes!) It's an enormously complex face, even at that age.
This is like comparing a child's pudding cup with an elaborate gourmet dinner. (Sorry, that's harsh; it's been a long work week.)
But actually, to be really petty, even his hair is better!
