Final Fantasy XIII of course. It's the bigger franchise, it's more well known and sells well.

Star Ocean sells fairy well.  SO3 sold 1.3 million copies WW LTD

 

That was because when Square and Enix merged they ported the "director's cut" version to NA and EU... That is if you're talking about "Till the end of time"
