Definitely Rivals. Brent Hubbs, Rob Lewis, and the gang usually get the latest before anyone else. The War Room is worth the price alone. Plus, there are many other people in the know on the premium forum.
For a UT fan, I disagree that Scout is better for basketball than Rivals. Scout is arguably better with player rankings (which you don't have to be a subscriber to see), but if you're talking about basketball recruiting as it pertains to UT, you will get more, better, and faster info via VolQuest.
This looks like a Rivals promotion, but there really is no comparison. Brent and Rob are the best.
