In my opinion SR: TT is better in most aspects gameplay, graphics, driving, customization variety. SR2 is superior in customization depth and story. The gameplay is still fantastic in 2 but its not quite as good as three. City design is about equal.
The City in Saints Row 2 is bigger but I agree that's how I am with both games.
