I always find it impossible to guess at team succes, especially for a single game, or even series. Change the question to "who wins the Ross or Hart in an 82 game season" and I'd be more inclined to give it a go and pick among those players.
Because, any good, bad, medium team can beat any good, bad or medium team in hockey, especially over a single game. Roy may have a stinker and let in 7. Or Lidstorm may think he's Orr and score 5 goals. Lots of way a single game can play out.
I think in general, I prefer the individual makeup of team 2, but I'm not so sure they'd mesh well chemistry wise. I'm not sure Crosby/Ov/Jagr would have great chemistry, so if I had to choose I'd choose team 1, because I'd expect their forwards and defensemen to have better chemistry.
