Body Language is a big thing. If he is drooping, looking annoyed, frustrated, it rubs off on the rest of the team. Strauss has looked calmer. Micheal Vaughan had the ability to never looked fussed regardless of what was happening, his calm demeanour mean when others looked at him, and saw him relax, they would relax as well, which is very helpful in pressure situations. Strauss has look a bit confused, worried and annoyed at times, but he has been better than Ponting who has made it very clear he is annoyed, angry, irritated at his bowlers and even argues with the umpires. Not good signals to send a young side.
And by talking I don't mean the words he says. It's the body language again. Ponting looks animated, irritated, annoyed. Strauss, again, looks calmer, more relaxed. One would presume this means he is being more re-assuring to his players than Ponting, but that could be wrong.
Tactically, I can't judge as I haven't seen Strauss enough. Ponting has always appeared to be short on creativity when it comes to tactics and tends to not have a plan B or a plan C when his main plan goes wrong. Can't tell if Strauss is the same, but it could be.
