I don't have either ball, but have seen both in action.
I watched a very capable bowler throw a Rogue in a tourney this past weekend. Though he didn't score well with it, I believe the Rogue is probably the strongest ball Roto has ever made. Since he obviously couldn't control his ball, he didn't do well with it, but having said that, he also had more area on the lanes to play with, then anyone else that was there.
In my opinion it is even stronger, overall than a VG which I have always considered to be pretty strong as well.
I have seen the 2nd Dimension thrown in league play, for the past two weeks, and to me this is a very moderate, even arcing, strong rolling ball with excellent carry. Would probably be great on a sport shot, and a THS.
Hope this helps.
