Peter McGough hands down. His political views notwithstanding, if it was purely journalistic skills we are talking about, no one else can hold a candle to him. Plus his sense of humor is outstanding. Again, I'm not talking about his journalistic integrity, but just his writing / reporting skills. Honorary mention also goes to John little. As for the worst of the pile, several names, predominant among them Johnny Fitness (of Musclemag) come to mind.
