Actually, their very similar in how they play, and in stat results. In Brooks 2009/10 year, his last good year, he averaged 35 MPG, 19.6 PPG, 5.3 APG, 2.6 RPG, while averaging 43.2% overall, and 39.8% from the three. He also shot 82.2% from the line.
I.T. averaged 25 MPG, 11.5 PPG, 4.1 APG, 2.6 RPG, while averaging 44.8% overall, and 37.9% from the three. He shot 83.2% from the line.
So I don't think you can say that I.T. overall, is better than Brooks. I have no idea how well Brooks played in europe, but apparently it was pretty good. I have no idea who will start the season, but I think its highly possible that Brooks will be the eventual starter. It should make for good competition in training camp.
