Both are ok. I prefer the Door Slammers app myself, but both have issues.

Neither comes close to topping the PC game IHRA Drag Racing or the Burnout series by Bethesda Softworks in the late 90's, early 2000's. Closest thing to "real" racing I've ever seen in a sim.

Would be kind of cool to see something similar done with newer technology. I can't imagine it would be too difficult to expand on that architecture to be able to simulate Stock & SS classes.
